TwinMesh helps developing waste heat recovery system

With its working principle of a positive displacement machine the scroll expander is a real challenge for 3D CFD. Luckily, BOSCH knows where to look for experts in that field. CFX Berlin provides the right tools, and experience to take such a challenge. Find here a presentation on numerical simulation of a scroll machine using TwinMesh and ANSYS CFX.

Spotlight on the Impact of Mesh Resolution

In order to produce reliable computational fluid dynamics (CFD) results, the mesh resolution can have a severe impact on both, qualitative and quantitative simulation results.
In this short article we present data from three different cases where correct mesh resolution is inevitable. Read through the text, have a look at the data, and be stunned by the fact that a coarse mesh resolution and quality can give you poor and in the worst case unreliable results.
