Modelling and analysis of three-dimensional chemically reacting, radiating Casson-nanofluid flow: thermophoresis and Brownian motion effects

Abstract

In the presence of a porous material and a magnetic field, the authors of this work must evaluate the combined effects of chemical reaction and thermal radiation on a Casson-nanofluid flow in three dimensions towards a linearly stretched sheet. Using the Roseland approximation, which integrates the effect of thermal radiation into the energy equation, thermal radiation is included in this study. The governing equation with initial and boundary conditions is converted to dimensionless form by adding pertinent non-dimensional variables and parameters, and then numerically solved using the finite element method. The effects of key variables on velocity, temperature, and concentration are shown graphically, followed by tabular representations of the effect of these parameters on skin friction, Nusselt, and Sherwood numbers and an in-depth explanation. This is essential for several technological applications, such as oil heat recovery, termite welding, transpiration cooling, and drag reduction. A comparison of our numerical results with previously published data reveals a high degree of agreement between the two sets of information. This new research has implications for energy systems, biomedical engineering and aeronautics, and has significant implications for the food industry.
