Capturing the baroclinic effect in non-Boussinesq gravity currents
Direct numerical simulations of two-dimensional gravity currents with small and medium density variations are performed using different non-Boussinesq buoyancy approximations. Taking the full low-Mach-number approximation as the reference, the accuracy of several buoyancy terms are examined. It is f...
