 The computation is on a 2D heated back-facing step flow. The temperature of the bottom and top walls is imposed to $T_c$ and the temperature of the step walls is $T_h$. The inflow is fixed with an uniform velocity profile $U_b$ at temperature $Tc$. We consider an incompressible flow under the Boussinesq hypothesis : the physical properties are constant and the thermal buoyancy effect is modelised by the Boussinesq hypothesis :
 $F_b= -\rho_0.\beta.g_0.(T - T_0)$ (see the page [[ Gravity_Namelist | Gravity ]] for more details).
-We suppose the fluid as a perfect gas. As a consequence, $\beta= \frac{1}{T_0}$
+We suppose the fluid is air that behaves as a perfect gas. As a consequence, $\beta= \frac{1}{T_0}$
