PULSATING FLOW AND HEAT TRANSFER IN A CHANNEL WITH SUDDEN EXPANSION
 
Resumo :
ABSTRACT. NUMERICAL INVESTIGATIONS OF PULSATING LAMINAR FLOW IN A PLANE CHANNEL WITH SUDDEN EXPANSION HAVE BEEN CARRIED OUT BY SOLVING 2D NAVIER-STOKES AND ENERGY EQUATION FOR AN INCOMPRESSIBLE FLUID. PULSATION HAS BEEN IMPOSED ON THE AXIAL VELOCITY AT THE CHANNEL INLET. RESULTS SHOW AN ASYMMETRY IN THE FLOW AND FOR CERTAIN AMPLITUDES OF PULSATION THE AVERAGE WALL NUSSELT NUMBER CAN INCREASE OVER THE FLOW WITHOUT PULSATION. KEYWORDS: PULSATING FLOW, HEAT TRANSFER ENHANCEMENT, CFD, CHANNEL FLOW
