A stochastic model for the hydrodynamic force in Euler--Lagrange simulations of particle-laden flows
Aaron M. Lattanzi, Vahid Tavanashad, Shankar Subramaniam +1
Standard Eulerian--Lagrangian (EL) methods generally employ drag force models that only represent the mean hydrodynamic force acting upon a particle-laden suspension. Consequently,…

Fully resolved simulation of dense suspensions of freely evolving buoyant particles using an improved immersed boundary method
Vahid Tavanashad, Shankar Subramaniam
Fully resolved simulation of flows with buoyant particles is a challenging problem since buoyant particles are lighter than the surrounding fluid, and as a result, the two phases a…
