ENHANCED BIOCONVECTION ADJACENT TO PERMEABLE CYLINDER IN HYBRID NANOFLUIDS: BACTERIA DISTRIBUTION AND PHYSICAL FEATURES UNDER MAGNETIC FIELD INFLUENCE

The presence of motile bacteria within hybrid nanofl uids induces the phenomenon of bioconvection. The hybrid nanofl uid was subjected to the presence and distribution analysis of Bacillus cereus, Bacillus brevis, Salmonella typhimurium, and Pseudomonas fl uorescens. This study explains the theoretical analysis of a hybrid fl uid with nanoparticles and gyrotactic microorganisms subjected to induced magnetic fi eld in three dimensions. Using the group technique, the governing system of equations has been simplifi ed to a set of ordinary diff erential equations (ODEs). The present study was motivated by an investigation into the eff ects of several parameters. The Prandtl number Pr, magnetic parameter M, inclination angle γ, shape factor n, permeability coeffi cient kp, diff usion coeffi cient of microorganism Dn, Brownian motion coeffi cient DB, thermophoresis diff usion coeffi cient DT, and concentration diff erence δc are examples of such parameters. For diff erent fl ow regulating parameters, the modifi cation of physical quantities, such as temperature, velocity, nanoparticle characteristics, and the density of motile microorganisms, is observed with precise physical features
