Consider stagnation point potential flow over a flat plate as shown below on the left. The stream function for this flow is given by w=Ary where A is a constant. The origin O here is the stagnation point. (Note - You can use the stream function above to prove this. You may verify this if you desire additional practice). To this stagnation point flow we add a source of strength A which generates potential flow over bump as shown below on the right. This would simulate flow inside a heat exchanger, for example, when there is some form of mineral deposition. Another example would be a jet exhaust impinging on an object during take off. (a) Determine the bump height h. (b) Determine the surface streamline y.. (e) Write a script to plot the streamlines. Use A - 1 - 1. Plot 4, using a different. color. Highlight the location of the stagnation point. Hint: 4, has to pass through the stagnation point
