The incompressible Navier-Stokes solvers INS3DUP, developed at NASA Ames and USA-IN3, developed at Rockwell Science Center, have been enhanced to simulate fluid-flow problems involving conjugate heat transfer (conduction and convection). The codes have been validated by comparing with experimental data, other computations and analytic solutions. The potential for using these codes in the analysis of component heat transfer of power assemblies is shown.

Calculations of hypersonic turbulent flows over a spherically blunted cone, bicone and a cavity have been carried out using a modified Baldwin-Lomax zero-equation model and a new one-equation k-L model. A detailed evaluation of the models is presented by comparing computed kinematic eddy viscosity, length scale, skinfriction, heat transfer rates and wall pressure distributions with those obtained from experiments.
