The present study concentrates on squeeze MHD flow of Casson fluid between parallel plates surrounded by a porous medium. The influence of melting, viscous dissipation and thermal radiation on the heat transfer process is disclosed. The characteristics of mass transport are detected with chemical reactions. Suitable similarity transforms are used to convert the partial differential equations into a system of ordinary differential equations. The transformed equations are solved using the bvp4c matlab solver with the shooting method. Our present study concluded that fluid velocity has direct relation with melting parameter while it is reciprocally related to squeezing parameter and reverse scenario exhibited in temperature distribution. The behaviour of velocity profile, temperature profile and concentration profile of the fluid are illustrated graphically and widely discussed. Previously attempted numerical/semi-analytic approaches (RK-SM, Keller Box and OHAM) are used to validate present numerical solutions.
