Direct Numerical Simulation of Particle-Laden Homogeneous Isotropic Turbulent Flows Using a Two-Fluid Model Formulation
Abstract A DNS approach for Eulerian-Eulerian dispersed particles simulation is presented in which a stress term corresponding to the uncorrelated motion of dispersed particles is identified. Two models for this stress terms are proposed. The first model uses an isentropic approximation that relates the local amount of uncorrelated particle kinetic energy to the particle number density. The sec...
متن کاملThe GNAT method for nonlinear model reduction: Effective implementation and application to computational fluid dynamics and turbulent flows
The Gauss–Newton with approximated tensors (GNAT) method is a nonlinear model reduction method that operates on fully discretized computational models. It achieves dimension reduction by a Petrov– Galerkin projection associated with residual minimization; it delivers computational efficency by a hyperreduction procedure based on the ‘gappy POD’ technique. Originally presented in Ref. [1], where...
متن کاملNumerical Solution of Compressible Turbulent Flows Using Earsm Model
This article deals with the numerical solution of compressible turbulent flows in aerodynamics. Compressible turbulent flow is described by the system of Favre averaged Navier-Stokes equations, which are closed by the explicit algebraic Reynolds stress model (EARSM) of Wallin and Johansson. The averaged Navier-Stokes equations together with EARSM model of turbulence are discretized by the finit...
