Research and Professional Activities

  • Geophysical flows, Turbulence
  • Numerical methods, scientific computing

Doctoral Project (2014 - ): Waves and vortices in geophysical turbulence

  • Study of energy cascade and interaction between wave and vortical modes in shallow-water turbulence.
  • Modified shallow-water equations to study shallow water turbulence sans shocks.
  • MILESTONE project: Mixing and length scales in stratified turbulence.
  • Core developer: FluidDyn project on Bitbucket

Graduate Project (2013 – 14): Mixed convection instabilities with and without Boussinesq approximation

  • Study on the effect of heating and cooling on flow instabilities leading to transition in mixed convection regime by using DNS and through linear viscous and inviscid stability theories for mixed convection
  • A newly developed energy based receptivity approach.
  • Developed a code based on compressible NS equation to validate the above results in a variable density Non-Boussinesq formulation.
