Bioconvection transport of magnetized micropolar nanofluid by a Riga plate with non-uniform heat sink/source

Abstract

The purpose of this work is to discuss the 2D bioconvective micropolar nanoliquid transport with thermal radiation and non-uniform heat sink/source through the Riga plate. Novel features of activation energy are considered. In addition, the Buongiorno nanoliquid transport model is incorporated, which includes Brownian and thermophoresis diffusions aspects. By using effective transformations, nonlinear expressions in the present flow model are transformed into higher-order ODEs. The obtained ODEs are then computed by utilizing an innovative bvp4c solver (shooting scheme) in MATLAB tool. The outcomes of velocity, temperature, concentration, and microorganisms are discussed. Velocity is reduced for growing magnitudes of magnetic and bioconvective Rayleigh numbers. Velocity field boosts up for improvement in Marangoni ratio parameter. The micro rotation profile diminishes for magnetic parameter, and it enhances for micro rotation parameter. The presented findings show that upgraded thermal conductivity of nanoliquid is very useful in medication delivery, medication, food manufacturing, safer cooling surgery, cooling reactors, oil and gas, nanotechnology, biological engineering, heat storage systems, magnetic cell isolation, biosensors, biotechnology, pharmaceutical, and military fields.
