Large eddy simulation of compressible channel flow
… resolvable scale motions from the unresolvable (subgrid) scales by applying a spatial filter to the compressible Navier-Stokes equations. The Leonard and cross terms which appear due to the filtering procedure are modeled based on a Taylor series expansion. The subgrid scale Reynolds terms are …

A locally conservative variational multiscale method for the simulation of porous media flow with multiscale source terms
… physical processes may be different at different scales. Numerical methods should therefore reflect the multiscale character of the solution. We concentrate on the development of simulation techniques that account for the heterogeneity present in realistic reservoirs, and have the ability to solve …

Large eddy simulations of hydrogen/methane jets in crossflows under engine-relevant conditions
… fuel consumption rates and chemical and flow timescales of a methane jet. At atmospheric pressure, the addition of methane broadens the flame and reduces the local heat release rate due to changes in chemical kinetics and mixing, with the peak value decreasing by approximately a factor of two as …
