Natural, mixed and forced convection in a vertical channel with asymmetric uniform heating
Abstract
The development of laminar mixed convection between vertical parallel plates with uniform but asymmetric heating is investigated numerically using a finite difference method. When forced convection aids free convection, a relation between the maximum wall temperature and the Reynolds number makes it possible to determine the prevailing natural, mixed, and forced convection zones. When forced convection opposes free convection, the fluid may flow downward if the forced convection is sufficiently strong and is produced by a mechanical device. Relations between the Reynolds number and the forced convection parameter are given and discussed for the cases where the fluid flows upward and downward.
