Non-uniform heat source/sink effects on the three-dimensional flow of Fe3O4 /Al2O3 nanoparticles with different base fluids past a Riga plate

Abstract

Abstract In this study we showed the numerical analysis on the steady, three dimensional flow of different nanofluids past a Riga plate with non-uniform heat source/sink effects. Similarity transformations were used for the conversion of the partial differential equations that govern the flow to the ordinary differential equations. Owing to the complexity in solving these non-linear ordinary differential equations, we employ Runge-Kutta method of fourth order in association with shooting iteration procedure. The three-dimensional flow fields influenced by the parameters pertaining to this problem is discussed with the graphs and tables. The computations on the physical quantities of interest were also performed. The results end up to signify that the local skin friction coefficient enhances for modified Hartmann number and the local Nusselt number is diminished for larger values of heat source/sink parameter. A comparison between the numerical results and already existing data has been done and was found to be in good quantitative agreement.
