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 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.
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.

Calculation of the blood flow in a novel ball valve for the application
in blood pumps. The results of the CFD calculations are a significant
component for the optimization of the design with the goal to reduce
blood flow velocity, stagnation areas and shear stresses.
