An unsteady MHD flow of nonlinear radiative heat transfer of Casson liquid over a contract cylinder has been modeled. This is a theoretical study that involves mathematical approach to do the investigation. The nonlinear partial differential equations for heat transfer are solved numerically using the RKF-45 method. Effects of embedded kinetic parameters on the velocity and temperature of the system are depicted graphically and discussed accordingly. It is found that the rate of cooling is much faster for higher values of unsteadiness parameter. The higher value of unsteady parameter decreases the profiles of velocity and temperature. Further, thermal boundary layer thickness is decreased when the Prandtl number increases.
