Thermophoretic particle deposition in bioconvection flow of nanofluid with microorganisms and heat source: Applications of nanoparticle and thermal radiation

Abstract

This research examines the flow of thermally radiative bioconvective nanofluid ( T i O 2 / W a t e r ) with microbes and thermophoretic particle deposition over a sheet, incorporating a non-uniform heat source. There are many important uses for studying the behavior of thermophoretic particle deposition in the bioconvective flow of nanofluids containing microorganisms. It helps to improve nanotechnology-based procedures where exact control over nanoparticle deposition is essential, including tailored drug delivery. Energy systems, environmental biotechnology, and biomedical engineering can all benefit from this model since it improves our comprehension of how nanoparticles behave in the presence of heat and microbes. It also encourages improvements in the control of thermal radiation, which raises the effectiveness of solar energy devices and cooling systems. Based on non-uniform heat source, electrophoretic and thermophoretic particle deposition, the present work investigates momentum, concentration, temperature flow, and microorganism distributions. Using suitable similarity variables, all equations to the proposed flow are converted into the ODEs. The reduced equations are evaluated using the RKF-4th 5th method. The properties of significant parameters on velocity, energy, solutal and microbiological profiles are determined with the support of graphs. The thermal distribution performs better with an increase in the thermal radiation. A contrary behavior is observed on the concentration profile when the values of electrophoretic and thermophoretic parameters increase. This study enhances knowledge across disciplines including healthcare diagnostics, chemical engineering, and ecological restoration by offering fresh perspectives on the dynamics of fluid movement and the transportation of particles.
