其他摘要：This paper presents a finite difference solution to the heat conduction-forced convection conjugate problem inside circular pipes with radial injection or suction through the porous pipe walls. The main objective of this work is to calculate the effect of the fluid inlet angle through the permeable wall on the energy transport and on the wall shear stresses in the liquid-solid interface. Aditionally. an analysis to find an eficient way to incorporate in the numerical algorithm different types of boundary conditions in terms of the stream function and on the vorticity is developed.
