Plasma generation, by means of AC or DV electrical discharges or optical laser breakdown, is used to control the flowfield of simple atmospheric flames, subsonic and supersonic boundary layers, and supersonic base flows.
The laboratory is involved in the computation, analysis, and modeling of turbulent flows. Traditionally, high-fidelity simulation methods like direct numerical and large-eddy simulation have been restricted to fairly simple geometries and flow physics.
We are developing numerical methods, turbulence models and simulation tools that are flexible enough to handle multi-physics flows in engineering geometries without compromising the accuracy needed to simulate turbulence.
Most of our simulations use unstructured grids on massively parallel computing platforms. Group members perform hands-on work on developing state-of-the-art algorithms, which they implement into parallel simlation codes and use to perform simulations on some of the largest parallel computers in the country.
The simulation results are then examined to elaborate on the underlying flow physics. The MPCUGLES software has the accuracy to perform benchmark calculations of fundamental flows, as well as the flexibility to simulate highly complicated engineering geometries. We conduct research into a variety of applications including: We are always interested in hiring strong new members to our group.
Please contact Professor Mahesh if you are interested. The laboratory is presently leading a multi-university project on turbulent cavitating flows.

An open source CFD tool, OpenFOAM is used to model the complex flow of a jet-atmosphere interaction. The flow fields are computed by the steady 3-dimensional Navier-Stokes solver with k-! SST turbulence model.
Our solver is validated with the experimental pressure. Supersonic jet and crossflow interaction: Computational modeling. The domain for jet in supersonic crossflow (referred to as JISC) extended 5 diameters upstream and 5 diameters downstream, 4 diameters in the spanwise direction and diameters in the wall-normal direction.
