Thermal contact properties

Thermal interaction at the surface of a body:

  • can be included in heat transfer problems (Uncoupled heat transfer analysis, Fully coupled thermal-stress analysis, Fully coupled thermal-electrical-structural analysis, and Coupled thermal-electrical analysis);

  • can involve conductive heat transfer between surfaces;

  • can involve radiative heat transfer between surfaces when the surfaces are separated by a narrow gap;

  • in Abaqus/Standard can involve convective heat flow across the boundary layer between a solid surface and a moving fluid;

  • can involve heat generated by frictional work in fully coupled thermomechanical or fully coupled thermal-electrical-structural simulations; and

  • in Abaqus/Standard can involve heat generated by an electrical current (Joule heating) in fully coupled thermal-electrical and fully coupled thermal-electrical-structural analyses.

General radiative heat transfer between surfaces is not discussed in this section. For information on modeling these types of problems in Abaqus/Standard, see Cavity Radiation in Abaqus/Standard. The thermal contact property models described here are for bodies in close proximity or in contact. For these problems gap radiation may be more efficient and robust than cavity radiation.
