ME4240 :Gas Dynamics Home Work 5, Due Friday the 13th of November November 5, 2009 1. A wedge of 25 degree half-angle is immersed in a supersonic flow. Flow visualizations indicate that the oblique shock wave is attached and is at an angle of 50 degrees to the incident flow. Based on this information calculate the Mach number of the incident supersonic flow. 2. Calculate the maximum surface pressure (in N/m 2 ) that can be achieved on the forward face of a wedge flying at Mach 3 in standard sea level conditions ( P atm =101325 N/m 2 ) with an attached shock wave. 3. Consider the supersonic airflow between two parallel walls at M =2.2, p =45kPa and T =300K. A positive deflection of 24 o is imposed on on of the walls as shown in Figure 1 (a) Draw the waves produced by the deflection and the interaction with the opposite wall. On the same drawing also draw the streamlines. (b) Calculate the flow properties past the reflected wave: Mach number, static and total pressure, total temperature and entropy change.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
