HOMARD : thermal stratification

French version

Balle rouge Description

This example shows a thermal stratification in a water current.
Fluid enters at the high left part of the structure. It goes down and the outlet is at the high right part. Because of temperature differences, the volumic mass of the fluid is not uniform. Therefore, gravity forces create stratification.

For that class of calculations, it is well known that the major difficulty is the accuracy of the computation near the zone of high variation of the temperature. Mesh adaptation techniques allow a mesh refinement where the temperature gradient is high. On this picture, the mesh can be seen with colors related to the temperature level, from the beginning of simulation to the steady state.
