Research Interests

Professor Mahesh's group is involved in the computation, analysis, and modeling of turbulent flows. The overall focus is on fundamental advances in numerical algorithms, and understanding of flow physics that allow the prediction of multi-physics engineering flows. Traditionally high- fidelity simulation methods like direct numerical and large-eddy simulation have been restricted to fairly simple geometries and flow physics. Dr. Mahesh's research focuses on developing numerical methods and turbulence models that are flexible enough to handle engineering geometries and complex physics without compromising the accuracy needed to simulate turbulence. Most of their simulations use unstructured grids on massively parallel computing platforms. Professor Mahesh conducts research into applications including propeller flows, hydroacoustics, cavitation, superhydrophobic surfaces, flow around maneuvering bodies, particle-laden flows and jet mixing.
