NUMERICAL INVESTIGATION OF FLOW CHARACTERISTICS OVER DIMPLED SURFACE

ABSTRACT
Flow characteristics over dimpled surface are studied numerically for a fully developed turbulent channel. The results show that dimples can effectively activate the near wall turbulence and cause an increase of total drag. The dimple depth also plays an important role in enhancement of hear transfer.
