16. The Axisymmetric Turbulent Wake
Abstract : This thesis presents a theoretical and experimental study of the turbulent axisymmetric wake. In the theoretical part, an equilibrium similarity solution of the far wake was derived that was found to admit to two different solutions for this flow. READ MORE

17. Global Turbulent EquiPartition (TEP) in Tokamak Plasma
Abstract : We studied analytically and numerically the establishment of global turbulent equipartition (TEP) of magnetised electrons in a tokamak plasma. This allows us to investigate self-consistently the inhomogeneous distributions of the plasma density, the electron and the ion temperatures, the generation of radial electric field and the poloidal and the toroidal rotation in the turbulent tokamak plasma.

18. Statistical Aspects of Diffusion in Turbulent Plasmas
Abstract : In this work we address the closure issue in kinetic and fluid descriptions of turbulent plasmas. In fluid description contribution has been made to the nonlinear closure by Mattor and Parker [Phys. Rev. Lett. READ MORE

19. Turbulent and neoclassical transport in tokamak plasmas
Abstract : One of the greatest challenges of thermonuclear fusion is to understand, predict and to some extent control particle and energy transport in fusion plasmas. In the present thesis we consider theoretical and experimental aspects of collisional and turbulent transport in tokamak plasmas. READ MORE

20. RANS Simulations of Interaction between Premixed Flame and Turbulence using OpenFOAM Library
Abstract : Unsteady multi-dimensional numerical simulation of turbulent flames is a widely recognized tool for research and development of future internal combustion engines capable of satisfying stringent requirements for ultra-low emission and highly efficient energy conversion. To attain success, such simulations need, in particular, elaborated CFD software and predictive models of turbulent burning. READ MORE
