Consider uniform flow past a circular cylinder with negative circulation as that shown in Figure of the course note. Calculate the pressure field, and the force on the cylinder for the four cases shown in the figure. (a) ro, stagnation points at 0 = 0 and 'Il with r=a. (6) P<0.₂ <1, Va Lift there exist two stagnation points with Ti < 0, < 271 On Ya |va| = 1, there exists only one stagnation point at r=a and O₂ = 377/a. (d) p<0, || > 1, 기, (c) 「<O, there exists no stagnation point on the surface of the cylinder. Sketch of the flow for different situation. The point "s" represents the location of the stagnation point.
