Thermal phototactic bioconvection in an isotropic porous medium heated from above
S. K. Rajput, M. K. Panda, A. Rathi
This study investigates thermal phototactic bioconvection in an isotropic porous medium using the Darcy-Brinkman model. The top boundary of the medium is exposed to normal collimat…
Effect of oblique irradiation on the onset of thermal phototactic bioconvection in non-scattering medium
S. K. Rajput, M. K. Panda
The linear stability of a suspension of phototactic algae is investigated numerically with particular emphasis on the effects of the angle of incidence of the illuminating oblique…
Effect of oblique irradiation on the onset of thermal-phototactic-bioconvection in an isotropic scattering algal suspension
S. K. Rajput, M. K. Panda
In this study, our focus is mainly to check the effect of light scattering on the onset of thermal-phototactic-bioconvection in an algal suspension where the suspension is illumina…
Effects of forward scattering on the onset of phototactic bioconvection in an algal suspension under diffuse flux without collimated flux
S. K. Rajput, M. K. Panda
Phototaxis refers to the directed swimming response influenced by the sensed light intensity in microorganisms. Positive phototaxis involves motion toward the light source, while n…
Phototactic bioconvection in an algal suspension with a free top wall due to diffuse flux in the absence of direct collimated flux
S. K. Rajput, M. K. Panda
In this article, the effect of diffuse flux in the absence of direct collimated flux on the onset of phototactic bioconvection is investigated. The main effect of diffuse flux in t…
Effect of heating or cooling in a suspension of phototactic algae with no-slip boundary conditions
S. K. Rajput, M. K. Panda
In this study, we investigate the impact of heating or cooling in a suspension experiencing phototactic bioconvection. The suspension is illuminated by collimated irradiation from…
Effect of Rotation in an Isotropic Scattering Algal Suspension with Oblique Collimated Irradiation
S. K. Rajput
The linear stability of a suspension of isotropic scattering phototactic algae is investigated numerically with particular emphasis on the effects of Taylor number in the rotating…
