Research Areas of Interest

 

  My research primarily deals in

• Computational fluid dynamics and heat transfer.

• LES, RANS and Partially-Averaged Navier-Stokes (PANS) approaches.

• Renewable energy.

Research Achievements

• Authored eleven review articles in leading international journals covering a wide range of topics on turbulent fluid flow, heat transfer and energy.

• Authored (single) an international book “Tackling Turbulent Flows in Engineering” published by Springer, Germany in the year 2011.

• Performed a detailed assessment on the effectiveness of the Partially-Averaged Navier-Stokes (PANS) approach, a variable resolution turbulence modelling technique proposed recently, to various flow configurations involving heat transfer (turbulent round plume, turbulent separated flow past a heated square cylinder and turbulent melt flow in Czochralski crystal growth process).

• Wide experience in mathematical modelling and computation of turbulent flows and heat transfer using LES, PANS and RANS approaches, covering many branches of engineering, including mechanical, civil, aerospace and chemical, etc. Research group has expertise in employing various commercial CFD packages, OpenFOAM and developing in-house source codes for investigating turbulent fluid flow and heat transfer in several flow configurations.
