Abstract
Numerical experiments have been performed to study the effect of nonuniform blowing or suction through the porous wall of a circular pipe with a constant heat flux at Us outer surface on the conjugated heat transfer. The Navier-Stokes equations were solved by using the vorticity -stream function formulation and a finite differences alternating direction implicit method. The results show the effect of both the angle and the velocity profile of the incoming flow through the porous wall on the internal wall temperature, Nusselt number, and wall shear stresses for nonisotkermal laminar flows with Péclet numbers between 10 and 1000.
