Calculational method for combined natural circulation and forcedconvection flow in a channel
Abstract
A finite element solution is presented for combined natural circulation and forced convection flow in a channel. Because the buoyancy force plays an important role in a mixed convection flow, an iteraction scheme was used in solving the coupled energy momentum equations. The momentum equations and the pressure equation are solved to calculate velocity profiles instead of solving the momentum equations with the continuity equation. Though the pressure equation is obtained by using the continuity equation, the continuity principle is reinforced into the momentum equations and the pressure equation at each iteraction. Calculations are performed for the combined natural circulation and forced convection case and the forced convection only case.
