Abstract
⺠Mixed convection in upward channel flow with periodic temperature on the colder wall is numerically studied. ⺠The effects of Gr, Re, channel length, and wavelength of the periodic wall temperature are examined. ⺠A multi-cellular flow regime is observed, with features that match the periodicity of the boundary temperature distribution. ⺠The recirculations are enlarged with increasing Gr/Re and wavelength of wall temperature. ⺠Larger wall heat fluxes can be obtained than those in the case with uniform temperature at both walls.
