Effect of Porous Blowing and Suction on Aerodynamics and Heat Transfer in Separated Laminar Flow in Duct Behind of Backward-Facing Step

摘要

Being a powerful intensifier of friction and of heat transfer in gas and liquid flows the flow separation plays a vital part in kinetics of exchanging processes in nature and in technical applications. The porous blowing and suction are also powerful factors that determine the characteristics of these processes. In present work the influence of these factors on friction and on heat transfer in separated laminar flow in duct behind of backward-facing step is investigated in numerical experiment.
