Abstract
The reality of chemical response, changing viscosity, Soret, and Hall current, as well as Prandtl nanofluid, are discussed. The conventional mathematical approach of transformation is used for transforming the model equations into nondimensional form, and the consequent nondimensional partial differential equations are then solved using the explicit finite difference method. After a stability test, the data are plotted using the graphics programme TECPLOT-9. With the assistance of computer programming languages, the results appear for a number of dimensionless elements on velocity, temperature, and concentration profiles along with the local skin friction, local Nusselt number, and local Sherwood number. 6.6a with COMPAQ Visual Fortran. Graphs have been used to discuss the results. Finally, we determined that a Soret number diminishes the local skin-friction coefficient whereas the thermophoresis parameter and Brownian motion improve it. It has been shown that varying Nb, Nt, Rd, and S values increase the primary velocity. Prandtl number and magnetic parameter induced a reduction in temperature. The diagrams additionally present the streamlines and isotherms for various parameters.
