In the present work we study the asymptotic and short time stabihty of stratified shear flow analytically and numerically. The algebraic growth and instability of stably stratified inviscid couette flow is studied ...

A layer of fluid with a free-surface which is initially supercritical (local Froude Fr > 1), displays a near discontinuity in film-thickness at a location where the Froude number becomes unity. This is better known as ...

In the last two decades, Lattice Boltzmann Method (LBM) has emerged as an e cient alternative for hydrodynamic simulations. In LBM, a ctitious lattice with suitable isotropy in the velocity space is considered to recover ...

Clouds are one of the major sources of uncertainty in climate prediction (IPCC Fourth Assessment Report: Climate Change 2007). They play a significant role in transporting heat across the whole extent of the troposphere. ...

In the present work, we study the effect of off-source volumetric heating on a starting plume in an attempt to understand the fluid dynamics of clouds. Clouds play a major role in weather and climate. In the tropics cumulus ...

In the present study, we have implemented a three-dimensional direct numerical simulation (DNS) algorithm for the purpose of studying instability and transition in a Poiseuille flow with imposed unstable stratification. ...

Rarefied gas dynamics show marked deviations from Navier-Stokes dynamics, which make them interesting to study. This thesis on rarefied ’granular’ gas dynamics, aims to study a prototypical flow setup of smooth inelastic ...
