The coupling of forced convection inside a vertical pipe and natural convection outside the pipe is investigated for the case where the pipe is surrounded by permeable insulation. This analysis is pertinent to the design of insulation jackets for pipes, where the insulation can be modeled as an isotropic porous medium. Attention is given to the cases of both parallel flow and counterflow. The heat transfer through the pipe wall is a direct result of the interaction between the forced convection outside the pipe and the natural convection outside the pipe. 9 refs.
