Abstract

A theoretica investigation is carried out for a convective heat transfer in a tube with periodically located protrusions. The investigation is performed by means of multiblock computational techniques for Reynolds equations solved with factorized finite-volumetric algorithm. These equations are closed using Menter transfer tangent tension model as well as energy equation for different scale intersecting structured grids.
