| Abstract: | The problem of condensation by mixed convection in a vertical channel has been numerically analyzed for an air water system.
The plates of the channel are subjected to uniform but different heat fluxes. The effects of ambient conditions on the condensation
process are investigated. The results show particularly the existence of a particular temperature called inversion temperature
for condensation. This temperature is defined as the temperature above it the condensation rate is higher for a lower vapor
concentration. It was found that this temperature increases with the increase of the ambient pressure and decreases with the
cooling heat flux. |
