Filtered models for reacting gas–particle flows

Modeling of filtered heat release for large eddy simulation of compressible infinitely fast reacting flows

A priori and a posteriori studies for large eddy simulation of the compressible turbulent infinitely fast reacting shear layer are presented. The filtered heat release appearing in the energy equation is unclosed and the accuracy of different models for the filtered scalar dissipation rate and the conditional filtered scalar dissipation rate of the mixture fraction in closing this term is analy...

Filtered Density Function for Large Eddy Simulation of Turbulent Reacting Flows on Unstructured Meshes

Domain Decomposition Methods for . . . of Reacting Flows

Domain decomposition is a natural route to parallel computing for partial differential equation solvers. In this procedure, subdomains of which the original domain of definition is comprised are assigned to independent processors at the price of periodic coordination between processors to compute global parameters and maintain the requisite degree of continuity of the solution at the subdomain ...

Dynamic Models for Subgrid-scale Transport and Mixing of Reactants in Atmospheric Turbulent Reacting Flows

Large-eddy simulation (LES) can provide valuable highresolution spatial and temporal information required to study the effects of turbulent transport and mixing on the chemical transformation of reacting scalars in the atmospheric boundary layer (ABL). LES consists of explicitly resolving all scales of turbulent transport larger than the grid scale (on the order of tens of meters in the ABL), w...

Multiphysics models and simulations for reacting and plasma flows applied to the space exploration program

This paper summarizes the current efforts at VKI and collaborating institutions in understanding nonequilibrium phenomena in hypersonic flows. Research activities related to “Detailed gas chemistry models,” “Kinetic theory,” and “Rarefied gas effects” are described.
