Abstract

ABSTRACT The objective of the current investigation is to examine the influence of buoyancy force, heat source, Brownian motion, thermophoresis, chemical reaction, transverse magnetic field and convective boundary condition on flow of tangent-hyperbolic nanofluid through an upright microchannel. The nonlinear partial differential equations are changed into ordinary differential equations by means of similarity transformations. The RKF45 method along with the shooting technique is used to solve the fluidic system numerically. The Buongiorno model is considered to observe the influence of thermophoresis, Brownian motion and chemical reaction with mixed convection. Graphical and numerical illustrations are presented to visualize the behavior of different parameters of interest on velocity, temperature, concentration and entropy generation of the flow system. The substantial findings of this study have been recorded as the amplification in the thermal and solutal Grashof number causes an increment in the flow rate in a channel, the thermal energy builds up with Brinkman number and heat source parameter, another significant outcome of the present analysis is that there is a downfall in the concentration field with the strengthening of thermophoresis parameter.
