Abstract

A numerical calculation is performed to study the effects of buoyancy force on the heat transfer characteristics of laminar forced convection flow in inclined parallel plates with the upper part cooled and the lower part heated uniformly. Numerical results are presented for the Reynolds number ranges from 4.0 10-3 to 1.13 10-1, the angle of inclination, , from 0 to 90 degree, and Pr of the high viscosity fluid is 909. It is found that the flow pattern of mixed convection in inclined parallel plates can be classified into four patterns which affected by Reynolds number and the angle of inclination.
