ScalarTransportFoam

This application solves the complete unsteady transport equation (convective + diffusive) for a passive scalar in an incompressible fluid:

$\frac{\partial T}{\partial t} + \nabla \cdot \left(\varphi T\right) - \nabla^2 \left( D_T \cdot T \right) = 0$

where $\varphi = U$ and $D_T$ is a constant.
