Recent experiments have shown that suspensions of swimming micro-organisms are characterized by complex dynamics involving enhanced swimming speeds, large-scale correlated motions and enhanced diffusivities of embedded ...

We examine the linear stability of a homogeneous gas solid suspension of small Stokes number particles, with a moderate mass loading, subject to a simple shear flow. The modulation of the gravitational force exerted on the ...

The nocturnal boundary layer(NBL) that develops over land is important in weather forecasting, climate modeling and in the dispersion of pollutants. Physical transport mechanisms such as radiation and turbulence play a ...

The main focus of this thesis has been to understand the dynamics of salt-diapiric structures and the role of various parameters that govern the diapir structures with the help of Rayleigh-Taylor fluid instability. ...

The flow past inline oscillating rectangular cylinders is studied numerically at a Reynolds number representative of two-dimensional flow. A symmetric mode, known as S-II, consisting of a pair of oppositely signed vortices ...

A global stability study of a divergent channel flow reveals features not obtained hitherto by making either the parallel or the weakly non-parallel (WNP) flow assumption. A divergent channel flow is chosen for this study ...
