The surface of the cooling coil becomes dry, wet or partially wet depending on the operating condition. Thus, a proper design of the cooling coil should include a heat transfer analysis on dry, wet or partially wet surfaces. In this study, an elementary model, which analyzes the cooling on an elementaty basis, is proposed. Comparison of the predict...

In the present work, we study, numerically, mixed convection flows in an open U-shaped channel as an application to a Soil – air exchanger (Canadian well). The channel is submitted to a vertical jet of fresh air from the right opening (ambient air) at a cold temperature (winter) Tc, while the walls are heated according to the depth of channel. We w...
