Physics of Turbulence through Computational and Analytical Tools

Dr. M.K. Verma, Department of Physics

Turbulence is one of the unsolved problems of science and engineering.  In our research we attempt to decipher the universal features of turbulence through computational and analytical tools.  We have developed a general-purpose parallel spectral solver named Tarang to solve fluid, magnetohydrodynamic, and convective turbulence.  Using Tarang we are investigating energy spectra and fluxes (similar to Kolmogorov's theory of turbulence), Nusselt number scaling, reversals in large scale flows, etc.    The simulations have been performed on large computing cluster, with runs going all the way up to 16000 processors.

We have also applied field-theoretic techniques to analyze the universal properties of turbulence.
