Approach for Coupled Heat Transfer/Heat Flux Calculations

Abstract

Coupled CFD/FE heat transfer / heat flux calculations for material temperature prediction with independent grids expose the need to exchange boundary condition information between the fluid and the solid domain. The author introduces a method of storing the boundary condition information together with the geometry information, where boundary conditions are represented by a set of geometric entities. This method of "virtual boundary conditions" simplifies some aspects of the coupled calculations by introducing a clear grid interface and enables a master model approach from the geometry generation (CAD) down to the analytical disciplines (CAE). The detachment of the boundary condition information from the computational grid also exposes advantages when considering different degrees of geometric complexity (2D/3D).
