Problem\/Description:
Conjugate heat transfer (CHT) simulation with respect to mesh morphing: The solid is moving with a solid body motion, the fluid domain is partly following by means of mesh morphing e.g. piston of an internal combustion engine. Monitoring \u2018areaInt(Wall Heat Flux )@Domain Interface 1 Side 1\u2019 at the fluid side of the moving CHT interface provides wrong values.
Solution: On a moving interface the wall heat flux values do include the complete enthalpy flux across the interface. They also contain the pressure work (Pressure*Area*Velocity) at the moving fluid\/solid interface. The correct wall heat flux is available at the solid side of the interface. Monitoring \u2018areaInt(Wall Heat Flux )@Domain Interface 1 Side 2\u2019 contains the right value.<\/p>\n","protected":false},"template":"","class_list":["post-157163","topic","type-topic","status-publish","hentry","topic-tag-ansys-fluent","topic-tag-cht","topic-tag-interface","topic-tag-moving-cht-interface","topic-tag-wall-heat-flux"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
