Characteristics of thermophoresis and Brownian motion on radiative reactive micropolar fluid flow towards continuously moving flat plate: HAM solution

The present objective of this study is to develop a mathematical model and rheological aspects by combining the micropolar fluid model to simulate the reactive flow from a continuously moving flat plate. The current flow model is formulated with employment Thermophoretic diffusion, Brownian motion and chemically reactive species. The focal micropolar based flow equations are transmitted into a non-dimensional form via similarity transformation for which Homotopy Analysis Method (HAM) is employed to obtain approximate analytical solutions. The role of numerous parameters on dimensionless flow phenomena are observed in very effective way utilizing graphical presentation. Various order of approximations for the convergence of HAM has been tabulated. Proper validation is conducted to show a strong relationship between our results with related published ones in literature with some limiting conditions. Furthermore, streamlines and isotherms are also plotted to know the pattern of the fluid flow. More so, the analysis shows that enhancement in Thermal Grashof number, solutal Grashof number and microrotation parameter rises the fluid spin rotation. Temperatures are suppressed with higher thermophoresis and Brownian parameters. Concentrations are elevated with higher thermophoresis parameter. Finally, the observations revealed that the presence of thermophoresis and Brownian motion is more effective to improve heat transportation phenomenon.
