Natural convection in partially heated square cavity

Mechanics, 2016
Numerical investigations were led in a square cavity (L=1), filled with air, of which a partially heated wall, by using a numerical code based on the finite difference method. The length of the heated part, at constant temperature, varies from 20 % to 80 % of the total length. The opposite vertical wall is supposed cold.
