An investigation is considered to examine the rotating boundary layer flow and heat transfer past a nonlinear shrinking surface in a nanofluid by taking into consideration the influence of the suction effect at the surface. Three kinds of nanomaterials namely titanium dioxide, copper, and aluminum oxide are considered. The governing equations in the form of partial differential equations (PDEs) for momentum and energy are converted into a system of ordinary differential equations (ODEs). The shooting technique built in the MAPLE program is applied to the resulting system of equations. The impacts of the embedded parameters which include rotation, nanomaterial volume fraction, nonlinear and suction on the velocities, temperature, coefficient of skin friction and the heat transmission rate are plotted graphically and have been discussed further. The outputs showed that the presence of rotation in the flow rises the coefficient of the skin friction as well as the heat transmission rate. It is also noticed that the nonlinear parameter accelerates the boundary layer separation in which the dual solution unites.
