This book discusses the numerical study of heat and mass transfer on Casson nanofluid flows over stretching surfaces. Our focus is to examine Casson nanofluid flow with influences of MHD, Radiation, Chemical reaction, non-Darcy porous media, and Electric field. The shape of the body has great control over the flow past a body and considerably effects the heat and mass exchange properties. So, the Fluid flow was studied on exponential stretching sheet, nonlinear stretching sheet, and moving plate with variable thickness. Throughout the study, the Keller Box method was utilised to analyse the flow and influences of various constraints numerically and graphically.
