Flow Simulation
Electronics
Design
Automation
Numerical simulation through Computational Fluid Dynamics (CFD) enables us to investigate and evaluate the flow characteristics of devices even before building a prototype and running an experiment. The simulation enables us not only to study the flow, but also heat transfer, phase changes and physical movement induced by the flow. |
The results of the CFD calculations make fast, cost saving optimization of the effectiveness of your developments in medical device technology possible. These calculations minimize the number of prototypes which need to be produced and considerably reduce the experimental complexity. |
Our Services |
In collaboration with you, we will analyze the
technical objectives, define the boundary conditions, and isolate the
parameters which need to be optimized.
Based on this, we will create the numerical model and conduct the numerical simulation for you. The results will be depicted numerically and visually in two dimensions, as particle pathlines and as movie clips. The visualization helps to improve the understanding of the flow phenomena in order to achieve a better design. The analysis and evaluation of the results enables us to give you recommendations for the optimization as well as for the design implementation of these ideas. The iterative recalculation of the flow using the revised geometry shows the achieved improvement of the relevant parameters. Our work results in the evaluation and the optimization of the flow characteristics and therefore of the effectiveness of your devices. |
