In the Navier-Stokes equations, the effects of rotation and transverse curvature on the flow on a rotating circular cylinder in an axial flow are estimated in terms of the Blasius variables, the Mangler-Falkner-Skan variables and the Seban-Bond variables. Three systems of boundary equations are obtained. The equations in terms of the Seban-Bond variables represent the radius effect more appropriately then the others. These equations are integrated for a prescribed external adverse pressure gradient and the difference in approximation is investigated. In each case, when the cylinder is rotating, the calculation proceeds beyond a separation point and terminates at a point where an internal singularity appears. The flow pattern, predicted by each of the equations, varies with the angular velocity of the cylinder in the same process. when the boundary layer grows, the higher order effect of the radius becomes significant.
