How to conduct Heat Transfer Analysis of Moving Solids?
When analyzing the heat conduction inside a moving solid, the following two settings are considered:
For the steady-state case, the solid zone is stationary. The fluid zone will set as a Moving Reference Frame. For the unsteady case, it is possible to move the grid (solid and surrounding fluid zone) with the Moving Mesh function. This solution will show the settings for both options.
