โœฆ Synopsis

An analysis has been developed to predict combined heat and mass transfer from an evaporating water film falling under gravity along a heated vertical plate with countercurrent air flow in the parallel-plate channel. The problem considered is related to numerous industrial processing operations and to containment cooling of advanced nuclear reactors. A low-Reynolds number k-s turbulence model is used in conjunction with combined heat and mass transfer analysis in an asymmetrically heated, parallel-plate vertical channel. The heated wall is wetted with a film of water that flows down by the force of gravity, and countercurrently flowing air cools the water film. The model predictions are first compared with available experimental data for the purpose of validating the model. The local heat fluxes, Nusselt, and Sherwood numbers are reported to obtain understanding of the physical phenomena.

## Abstract We measure heat transfer coefficients of natural convection between two vertical smooth parallel plates heated uniformly in the laminar, transition, and turbulent regions. The heat transfer characteristics are experimentally investigated with changing width, ฮด, between the vertical para
