ASSESS: Leading the Simulation Revolution

The changing role of Engineering Simulation is really about business benefits. However, achieving those benefits and the Engineering Simulation market's associated growth is tempered due to the lack of expertise available. Business drivers are forcing a "simulation revolution" to overcome the expertise-based limitations restricting the expansion of Engineering Simulation applications. The Simulation Revolution is about making Engineering Simulation widely available & appropriate to support improved decision-making throughout the entire life-cycle of engineered products and processes. We need a broad multi-industry initiative to raise awareness and develop/promote strategies to enable the Simulation Revolution.
The ASSESS (Analysis, Simulation, and Systems Engineering Software Strategies) Initiative was formed to bring together key players to guide and influence strategies for software tools for model-based analysis, simulation, and systems engineering.
This session will provide an update on the ASSESS Initiative completed and planned activities to support the Simulation Revolution.

CFD Simulation of an Axial Piston Pump with Ansys CFX

Thanks to their compactness and efficiency, swashplate axial piston pumps are widely used as fluid power sources in fixed and mobile applications that require high pressure and variable flow rates. In order to guarantee high performances, reliability and reduced time-to-market, their development process requires more and more the use of advanced simulation tools. With specific reference to fluid dynamic simulation, different approaches are available; nowadays, the most common one is still represented by the lumped parameter method (0D-1D models). The advantages of this approach are the fast computational time and the easiness to reach convergence, but some physical phenomena are inevitably simplified or even neglected at all. In this sense a three-dimensional approach is the most advanced and accurate method; nevertheless there are still considerable challenges to overcome before reach a comparable level of usability: CPU time and convergence issues, in order to solve complex transient analyses characterized by small clearances and high pressure drops.
In this work, a CFD model of fluid flow in an axial piston pump, working at high pressure, is presented. The presentation will show the workflow for the construction of the model in Ansys CFX and the model validation through quantitative comparison of predicted chamber pressures and fluid flows with those obtained with a validated 0-D model. Finally, an overview of phenomena related to spatial trajectory of oil jets inside the pump will be shown.

Modelling and Simulation of Environment Friendly Packaging Concept for Combi Boiler

The combi boiler is a heating appliance that is used for providing a heat power for central and domestic hot water lines. These type of devices are exposed to loads such as drop, vibration, temperature, and stack that may cause damage starting from production to end user. Drop is more pronounced when considering other damage factors in terms of the effect of damage and probability of occurrence. EPS is one of the commonly used packaging material to protect white goods and combi-type appliances from such damage mechanisms. However, with the environmental regulations that have come into effect in the European market, especially in the UK in recent years, restrictions are being made on disposable plastic-based materials. Therefore, environmentally friendly packaging material alternatives that can be used instead of EPS come to the fore.
In this study, a packaging concept with paper-based honeycomb material was designed for the combi boiler and numerical analysis of the drop test was performed using LS-DYNA software. The findings obtained from numerical analysis were compared for packaging concept designs realized with EPS and environmentally friendly packaging material. The energy absorbed by the packaging elements and the deformation levels transferred to the appliance were determined.In this context, by guiding the packaging system development process, design improvement suggestions were made. As a result, the appliance cost and time used for experimental testing are saved.

Highly motivated and knowledgeable about design, modelling and simulation in HVAC industry especially in residential heating. Closely follows technological developments in the field and reveals innovative new project ideas.

Multi-phase fluid-dynamic simulation in electric expansion valves for refrigeration and air conditioning applications

Electric expansion valve (EEV) is one of the most important devices in refrigeration and air conditioning applications and it has the purpose of taking the refrigerant fluid from the condensing pressure to the evaporating pressure. The aim of the present activity is the calculation of refrigerant capacity in order to populate Castel's EEV manual which allows the refrigeration equipment manufacturers to select the most suitable component for their applications.
An in-depth numerical investigation has been carried out with the suite ANSYS CFD and this led to geometrical modifications that allowed to reach the desired refrigerant capacity values and a better internal design of critical geometries. The main challenge of this numerical study was modelling the transition of the fluid phase from liquid to gas.
The low capacity values obtained with CAE technology have been experimentally verified by a refrigeration testing system owned by Castel’s laboratory.

After the degree in aeronautical engineering at Politecnico di Milano I started working as manufacturing engineer at UTC AEROSPACE SYSTEMS. This first experience allowed me to deal with a dynamic and innovative work environment and gave me the chance to deepen NADCAP program for the most common special processes used in the aerospace industry.
The second work experience was at MATTEI GROUP, a company which manufactures compressors. This period increased my knowledge in turbomachinery and in the rotary vane technology. The company where I have been working now is CASTEL, italian leading supplier of refrigeration and air conditioning components. My role as R&D Engineer is focused on new products desing, development of new technologies and laboratory activities. CASTEL provided me the great opportunity to widely deepen CAE technologies, this allowed me to become internal responsible both for CFD and FEM analysis.

Modified Lumped Modelling Approach for Simulation of Electrical Components in Switchgears

In electrical switchgears, heat generation due to electrical resistivity, eddy currents and contact resistance results in temperature rise. This temperature rise exceeding the allowable limits as prescribed in standards may lead to potential damage to electrical devices within the switchgear reducing its life and efficiency. In the recent times, there has been a tremendous impetus towards modelling of switchgears to reduce the design & development cycle time as the requirement of reduced footprint poses increased challenges to meet the thermal requirements.
A typical Low voltage switchgear consists of many electrical components such as busbars, ACBs, MCCBs, relays, contactors etc. Detailed modelling of switchgear systems along with these electrical components becomes difficult due to geometrical complexities and meshing constraints. Hence, general practice followed in industry is to model electrical components in full system modelling as lumped heat sources as per catalogues power loss data. This approach though computationally faster, jeopardizes the accuracy of temperature rise predictions as it doesn’t closely simulate the actual physics of heat interaction of the component with the neighboring environment in 3D simulations/modelling. Present work aims to develop a Modified Lumped Modelling approach that captures the distribution of heat dissipation from/within the component closer to reality without altering its interaction with the neighboring environment in 3D thermal simulations of full assembly. Experimental temperature rise test results of individual components is used to determine the distribution of heat loss from/within the component. Similar approach is then further extended to two or more components (e.g. MCCB and contactor), which are coupled in series in drawers of switchgear. This Modified Lumped Modelling approach when utilized in 3D modelling and simulation of complete switchgear system, results in improved accuracy without compromising computational time for different variations of switchgears based on Ingress protection, ambient conditions, ventilation systems for same combination of components inside a drawer. Simulation results for individual component, components coupled in series and switchgear system are validated with temperature rise tests. For individual component, the correlation coefficient is 0.98 and Absolute Average Deviation (AAD) is 5.1%; whereas for coupled systems, the correlation coefficient and AAD is found to be 0.96 and 10.79% respectively. For complete switchgear system the correlation coefficient and ADD are 0.93 and 5.84% respectively.

Swing check valve seat-clapper dynamic structural impact simulation using Ansys Autodyn explicit solver

Swing check valve seat-clapper dynamic structural impact simulation due to pipe rupture of the upstream pipeline, by means of Ansys Autodyn explicit solver (free for mechanical enterprise license) instead of classical LS-Dyna explicit one (not in mechanical enterprise license pool): a CFD analysis of the clapper shut off due to emergency condition was carried out in order to calculate the clapper impact velocity. At CFD simulation end, the swing is still open with a minimum gap. The clapper velocity in this position and the fluid dynamic torque (end condition of CFD analysis) are the initial condition of the dynamic structural impact finite element analyses. Normally the dynamic structural impact FE analyses were performed using Ls Dyna which is not in the Ansys mechanical license pool. The goal is to perform the analysis by Ansys explicit solver thus being in the Ansys mechanical enterprise license till 2018 for free.
