Consider the supersonic flow over a 5° half-angle wedge at zero
angle of attack, as sketched in figure below. The freestream Mach
number ahead of the wedge is 2.0, and the freestream pressure and
density are 1.01 × 105 N/m2 and 1.23 kg/m3, respectively (this
corresponds to standard sea level conditions). The pressures on the
upper and lower surfaces of the wedge are constant with distances
and equal to each other, namely, Pu = Pl = 1.31 × 105 N/m2....

4. Drag Coefficient. Fluid flows past the two-dimensional triangular wedge shown in Figure 3. The equilateral triangle has side length a, and a span length of 1 unit out of the plane. The pressures on both the front faces are constant values PA as shown in the figure, and constant value PB on the back face. The average shear stress on each of the front faces is Tavg Assume that the drag due to pressure is equal to the drag...

08 Question 2.7 Two possibilities are considered for the design of a two-dimensional jet engine inlet as shown in the figures (a-b) below. The inlet is to operate at the Mach number Mi, shown in the table below. In the first design configuration, shown in figure (a), the deceleration of the flow takes place through a normal shock. For the second case, shown in figure (b), a wedge-shaped diffuser is used to...

50 mph A long semi-circular hut with a 2.44 m (8 ft) radius is exposed to extreme windy conditions in a desert. The wind blows uniformly at a speed of 22.4 m/s (50 mph) as shown in the figure. The upstream pressure is atmospheric (gage pressure = 0). Determine the resultant drag and lift forces exerted on the hut due to the wind Assume the pressure inside the hut is also at atmospheric pressure Problem Description Questions What are the...
