The main objective of the present analysis is to study an enhancement of heat transfer in an unsteady rotating flow for the aqueous suspensions of single wall nanotubes under nonlinear thermal radiation. Appropriate transformations are implemented for the conversion of partial differential systems into a set of ordinary differential equations. The transformed expressions have been scrutinized through RKF-45 order method along with shooting technique. The impact of various pertinent parameters for the velocity and temperature fields are analyzed through graphs in detail. Also, the role of substantial parameters on the fiction factor and mass transportation rates is determined and conferred in depth through graphs. Our simulations established that the higher value of rotation rate parameter reduces the thickness of the momentum boundary layer thickness. Further, an unsteadiness parameter increases velocity and temperature profile decreases.
