Effect of imposed shear on the dynamics of a contaminated two-layer film flow down a slippery incline

Muhammad Sani, Siluvai Antony Selvan, Sukhendu Ghosh +1

The linear instability of a surfactant-laden two-layer falling film over an inclined slippery wall is analyzed under an influence of external shear which is imposed on the top surf…

Effect of floating flexible plate on the dynamics of flow over a mild-slope

Siluvai Antony Selvan, Sukhendu Ghosh, Harekrushna Behera +1

Hydrodynamic instability of a gravity-driven flow down an inclined plane is investigated in the presence of a floating elastic plate which rests on the top surface of the flow. Lin…

Rotational Instabilities in Stratified Miscible Layers

Saunak Sengupta, Sukhendu Ghosh, Sandeep Saha +1

Instability of stratified multi-phase flow in a rotating platform becomes important because of a potential role in micro-mixing and micro-machines. Centrifugal actuation can play a…

Rotational Instabilities in Microchannel Flows

Saunak Sengupta, Sukhendu Ghosh, Sandeep Saha +1

Mixing in numerous medical and chemical applications, involving overly long microchannels, can be enhanced by inducing flow instabilities. The channel length, is thus shortened in…
