For the ideal flow around a circular cylinder the equation for the stream function in 2D flow is: $$\psi = -V_0 \left(r - \frac{a^2}{r^2}\right) \sin(\theta)$$ Here $V_0$ is the undisturbed uniform velocity, $r$ is the radial coordinate, $a$ is the radius of the cylinder and $\theta$ is the angle measured from the back to the front of the upper part of the cylinder. a) Determine the velocity distribution along the surface of the cylinder. What is the velocity at $\theta = 90^\circ$? b) Determine the pressure coefficients distribution along the surface of the cylinder. What happens at $\theta = 180^\circ$? c) Calculate the Lift force on the cylinder.
