We deal with the study of momentum and heat transfer
characteristics in a second-grade rotating flow past a porous
plate. The analysis is performed when the suction velocity normal
to the plate, as well as the external flow velocity, varies
periodically with time. The plate is assumed at a higher
temperature than the fluid. Analytic solutions for velocity, skin
friction, and temperature are derived. The effects of various
parameters of physical interest on the velocity, skin friction,
and temperature are shown and discussed in detail.
