Resum
Numerical methods for fluxes with strong density variations but with speeds much lower than the sound speed, known as low Mach flows, present some particularities with respect to incompressible formulations. Despite having similar application ranges, incompressible formulations using the Boussinesq approximation with constant fluid properties cannot correctly describe fluxes with high density variations. According to Gray and Giorgini [1], use of the Boussinesq approximation can be considered va...
