The velocity field for steady inviscid flow from left to right over a circular cylinder, of radius R is given by V! =U cos θ 1− R r 2 " # ^er −U sin θ 1+ R r 2 " # ^eθ Obtain expressions for the acceleration of a fluid particle moving along the stagnation streamline ðθ =πÞ and for the acceleration along the cylinder surface ðr =RÞ. Plot ar as a function of r=R for θ =π, and as a function of θ for r =R; plot aθ as a function of θ for r =R. Comment on the plots. Determine the locations at which these accelerations reach maximum and minimum values.
