Flow dynamics in a wavy channel filled with anisotropic porous material under the effect of wall slip
Shyamal Kumar Mondal, Sougata Mandal, Sukhendu Ghosh
In this study, a theoretical and graphical analysis is conducted to examine the effects of wall-velocity slip, anisotropic ratio, and porosity parameter on a two-dimensional, visco…
Conservation laws, a new class of group invariant solutions, and its applications for the Whitham Broer Kaup model
Sougata Mandal, Sukhendu Ghosh
The Whitham Broer Kaup (WBK) equations provide a fundamental framework for modeling shallow water wave dynamics, effectively capturing both nonlinear and dispersive effects. In thi…
Stability of soluble surfactant-laden falling film over a hydrophobic incline in the presence of external shear
Dipankar Paul, Harekrushna Behera, Sukhendu Ghosh
The hydrodynamic stability analysis of gravity-driven, soluble surfactant-laden fluid streaming down a slippery, slanted plane in the presence of external shear force is being expl…
Instability behavior of odd viscosity-induced viscous fluid over a vibrating bed
Md. Mouzakkir Hossain, Mrityunjoy Saha, Harekrushna Behera +1
The manuscript focuses on the theoretical stability analysis of the viscous liquid over a vibrating inclined rigid bed when the fluid undergoes an impact of odd viscosity. Such an…
Hydrodynamic instability of shear imposed falling film over a uniformly heated inclined undulated substrate
Md. Mouzakkir Hossain, Sukhendu Ghosh, Harekrushna Behera +1
Linear and weakly nonlinear stability analyses of an externally shear-imposed, gravity-driven falling film over a uniformly heated wavy substrate are studied. The longwave asymptot…
Impact of a floating flexible plate on the stability of double-layered falling flow
Md. Mouzakkir Hossain, Sukhendu Ghosh, Harekrushna Behera
The hydrodynamic stability behaviour of a two-layer falling film is explored with a floating flexible plate on the top surface. The stress balance at the surface is modeled using a…
Odd-viscosity induced surfactant-laden shear-imposed viscous film over a slippery incline

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…
Coriolis force-based instability of a shear-thinning microchannel flow
Saunak Sengupta, Sukhendu Ghosh, Suman Chakraborty
Instability mechanism based on Coriolis force, on a rapidly rotating portable device handling shear thinning fluids such as blood, is of utmost importance for eventual detection of…
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…
Stability of viscosity stratified flows down an incline: Role of miscibility and wall slip
Sukhendu Ghosh, R. Usha
The effects of wall velocity slip on the linear stability of a gravity-driven miscible two-fluid flow down an incline are examined. The fluids have the matched density but differen…
