Diffused bounce-back condition and refill algorithm for the lattice Boltzmann method

Krithivasan, Siddharth; Wahal, Siddhant; Ansumali, Santosh (American Physical Society, 2014)

A solid-fluid boundary condition for the lattice Boltzmann (LB) method, which retains the simplicity of the bounce-back method and leads to positive definite populations similar to the diffusive boundary condition, is ...
DIRECT SIMULATION MONTE CARLO FOR DENSE HARD SPHERES

Chao, Liu; Kwak, Sang Kyu; Ansumali, Santosh (World Scientific Publ Co Pte Ltd, 2014)

We propose a modified direct simulation Monte Carlo (DSMC) method, which extends the validity of DSMC from rarefied to dense system of hard spheres (HSs). To assess this adapted method, transport properties of hard-sphere ...
Fokker-Planck model of hydrodynamics

Singh, S. K.; Ansumali, Santosh (American Physical Society, 2015)

We present a phenomenological description of the hydrodynamics in terms of the Fokker-Planck (FP) equation for one-particle distribution function. Similar to the Boltzmann equation or the Bhatnager-Gross-Krook (BGK) model, ...
