Non-homogeneous anisotropic bulk viscosity for acoustic wave attenuation in weakly compressible methods
Dheeraj Raghunathan, Y. Sudhakar
A major limitation of the weakly compressible approaches to simulate incompressible flows is the appearance of artificial acoustic waves that introduce a large mass conservation er…
