Flow of nanofluid fluid due to moving surface with variable viscosity and thermal conductivity

Abstract Owing to peak thermal consequences and stable properties, the nanofluids offer various kinds of applications in solar collectors, the automotive industry, air conditioning systems, renewable energy, the cooling of electronics, and so forth. Following such motivated applications in mind, the objective of current work is to analyze the improved characteristics of heat and mass transfer due to the interaction of nanofluids comprising the variable thermal features. The variable assumptions of nanofluid viscosity, thermal conductivity, Brownian diffusivity, and motile density have been carried out. The stability of nanofluid is ensured by the decomposition of microorganisms. The flow is subject to a porous, saturated, moving surface with mass suction effects. Additionally, the problem is updated by utilizing the chemical reaction and radiative effects. The governing equations are interrupted into dimensionless forms. The numerical solution is computed with the help of the shooting scheme. The results are interpreted physically for the involved parameters. It is assumed that the presence of porous media and suction effects leads to an improvement in the heat and mass transfer phenomenon. The assumptions of variable viscosity, thermal conductivity, and Brownian diffusivity are beneficial in enhancing the thermal transport process.
