A FFT-based finite-difference solver for massively-parallel direct numerical simulations of turbulent flows

, 2018
We present an efficient solver for massively-parallel direct numerical simulations of incompressible turbulent flows. The method uses a second-order, finite-volume pressure-correction scheme, where the pressure Poisson equation is solved with the method ...

Brownian dynamics of rigid particles in an incompressible fluctuating fluid by a meshfree method

, 2015
A meshfree Lagrangian method for the fluctuating hydrodynamic equations (FHEs) with fluid-structure interactions is presented. Brownian motion of the particle is investigated by direct numerical simulation of the fluctuating hydrodynamic equations.

Using the stress function in the flow of generalized Newtonian fluids through pipes and slits

, 2015
We use a generic and general numerical method to obtain solutions for the flow of generalized Newtonian fluids through circular pipes and plane slits. The method, which is simple and robust can produce highly accurate solutions which virtually match any ...
