Turbulence Research

The flow of fluid is governed primarily by three dominant features: 1. A pressure difference between two points induces fluid flow, 2. Change of fluid momentum (i.e., change in velocity of the fluid arising due to friction, gravity, etc.,) creates a flow of fluid, 3. Finally, an addition of energy to the liquid sets it in motion.

All these features that induce fluid flow are captured elegantly by Navier Stokes system of equations; however, such a system of equation cannot be solved analytically. This unavailability of analytical solution can be attributed to non-linear and coupled nature of this system of equations. This is where computational tools to create numerical solutions become essential. While there are several computational methods, my works focused on Large-eddy simulations. While I maintain my research interest on CFD, I am not currently active in CFD research. However, any discussions regarding my earlier works and exciting proposals to collaborate are appreciated.
