As a consequence of the thermal expansion, the velocity field is not divergence free. The system fully couples the momentum balance with non-linear advection-diffusion equation for temperature. The model is suitable for low speed flow simulations of the Newtonian, calorically perfect fluid, which obeys Fourier law. The algorithm is an extension of a well known semi-implicit scheme for incompressible Navier-Stokes equations in primitive variable formulation. Performance is tested on manufactured solution, what gives an overview to the temporal convergence. Comparison with experimental data is also presented.
