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…

A general pressure equation based method for incompressible two-phase flows
Hormuzd Bodhanwalla, Dheeraj Raghunathan, Y. Sudhakar
We present a fully-explicit, iteration-free, weakly-compressible method to simulate immiscible incompressible two-phase flows. To update pressure, we circumvent the computationally…
