Homotopy perturbation method (HPM) and Runge-Kutta fourth-order method with shooting technique have been performed to investigate the presence of thermal radiation on squeezing unsteady nanofluid flow between two lateral plates. The results obtained, are found in good agreement with the previously published studies which employed Duan-Rach Approach (DRA). We found that the fluid temperature is physically decreased with an increase in thermal radiation parameter.
