Abstract:
3D turbulent air flow and heat transfer developing in a two-pass square channel rotating in the orthogonal mode are simulated using the high-Re k-epsilon turbulence model and a recently developed modification of wall functions. Auxiliary problem for accurate definition of inlet boundary conditions formed by a long unheated upstream section is considered. Details of flow structure are presented. Local heat transfer results are compared with experimental data.
