Abstract.

A computer code was developed for modelling laminar mixed convection heat and mass transfer with the evaporative cooling of liquid film falling along an insulated vertical channel. The numerical method applied solves the coupled governing equations together with the boundary and interfacial conditions. Results are specifically presented for air–water system. Parametric computations were performed to investigate the effects of Reynolds number, inlet liquid temperature and inlet liquid mass flow rate on the liquid film cooling mechanism. The results indicate that the latent heat transfer is a main mechanism for heat removal from the interface. Additionally, significant liquid cooling results for the system with a higher gas flow Reynolds number Re, a lower liquid flow rate Γ0 or a higher inlet liquid temperature TL0.
