摘要

The authors present a numerical Investigation of turbulent mixed convection inside a wetted-wall tube. The mixture air and water vapor flows downwards the vertical tube. Turbulent momentum, heat and mass transfer equations combined with a low Reynolds number model are discretized by using the finite volume method. The algebraic system equations deduced from this discretization are solved with the Thomas and Gauss algorithms. Results show that the evaporative cooling of the wetted wall and the air flow through the tube can be produced by low heat flux applied to the tube wall.
