Fluid-mediated sources of granular temperature at finite Reynolds numbers
Aaron M. Lattanzi, Vahid Tavanashad, Shankar Subramaniam +1
We derive analytical solutions for hydrodynamic sources and sinks to granular temperature in moderately dense suspensions of elastic particles at finite Reynolds numbers. Modeling…
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,…
Particle-resolved simulation of freely evolving particle suspensions: Flow physics and modeling
Vahid Tavanashad, Alberto Passalacqua, Shankar Subramaniam
The objective of this study is to understand the dynamics of freely evolving particle suspensions over a wide range of particle-to-fluid density ratios. The dynamics of particle su…
Multiphase Flows: Rich Physics, Challenging Theory, and Big Simulations
Shankar Subramaniam
Understanding multiphase flows is vital to addressing some of our most pressing human needs: clean air, clean water and the sustainable production of food and energy. This article…
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…
