The unsteady free convection flow of second grade fluid in rotating frame with ramped wall temperature

In this paper, the unsteady free convection flow of second grade fluid in a vertical frame with ramped wall temperature is investigated. The governing equations are modeled in a rotating frame where both the fluid and frame rotate in unison with angular velocity. The exact solutions in terms of velocity and temperature are obtained analytically by using Laplace transform method. These solutions are presented graphically and discussed for second grade fluid parameter (α) and rotation parameter (ω).
