Employing the Douglas – Rachford Scheme to Simulate Convective Heat Transfer

In this new article, the R&D Department of Simmakers Ltd. focus on the modification of the Douglas – Rachford ADI scheme to account for convection in the computational domain.

We have included an example problem to compare the computational time using the ADI method with a high filtration velocity setting against the computational time without filtration. The temperature distribution is described by the partial differential equation of heat conduction where, in the case of convection, there is a so-called convective term. Since the computational domain is arbitrary, the heat equation is solved numerically via finite-difference methods (FDM).
