Splet1.2 Heat Transfer in OpenFOAM In OpenFOAM 2.1.x, several solvers can be found to simulate heat transfer. Heat transfer in solids can be simulated by solving the Laplace equation for the conductive heat transfer in a solid (laplacianFoam). For uids, di erent approaches are possible depending on if the uid is considered compressible or not. SpletThe implementation of a scalar transport equation in OpenFOAM (r) is straightforward due to its advanced C++ syntax. A few preliminary steps are necessary however to define the fields involved in the terms of the transport equation.
