This paper reports on a series of studies using COMSOL Multiphysics, carried out to investigate the phenomena of fully developed and developing laminar flows of a Newtonian fluid initially at constant temperature, between parallel plates and through circular tubes, where heat exchange takes place at the interface between the fluid and the plates or the tube wall.

Selected numerical results were compared with existing analytical solutions that were in turn computed using Maple.

The validated COMSOL models constitute excellent teaching and learning tools that contribute to and facilitate understanding of complex convection heat transfer problems.
