Effect of cross diffusion on MHD non-Newtonian fluids flow past a stretching sheet with non-uniform heat source/sink: A comparative study

Abstract

The present study sought to report the combined influences of frictional and irregular heat on MHD non-Newtonian fluid (Casson and Maxwell) flows due to stretched surface. The action of thermal diffusion and diffusion thermo is scrutinized. The flow will take place due to stretched surface. The equations determining the flow condition are transfigured as coupled equations through self similarity transmutations. R.K. Fehlberg technique is implemented to acquire the solution of the problem. Graphs are plotted to inspect the influence of sundry physical quantities on the three routine profiles of the flow field. Further, expressions are procured for friction factor along with the rate of heat and mass transfers and discussed comprehensively through tabular forms. Results indicate that Casson fluid attains highest velocity when compared with Maxwell fluid. The mass transfer rate in Maxwell fluid is better than that of Casson fluid whereas a dissimilar phenomenon is discerned in heat transfer rate. Also Eckert number and irregular heat parameters have tendency to exalt the fluid temperature.
