Abstract: The effects of wall suction on the mean flow and heat transfer in a pipe are studied numerically for two suction rates. The Reynolds averaged Navier-Stokes equations are solved in conjunction with linear and non-linear low-Re models of turbulence. Near-wall velocities and temperatures are increased with increasing suction rate. The excess skin friction coefficient and Nusselt number, resulting from suction, are found to be up to 9 times the respective one with no suction. Computed results are compared satisfactorily against experimental measurements performed by Schildknecht et al. (1979).
