Supersonic vehicles have particular shapes to better interact with the air that surrounds them. In supersonic airplanes, like the Concorde, we can see that the nose has a conical or almost conical shape, to take advantage of the three-dimensional relieving effects and improve the performance of the vehicle. In this simulation example we will analyze how the shape of a body can affect the flow characteristics
The objective of this simulation example is to learn how to simulate the oblique shock generated by an object with a sharp nose. This example will show how a wedge and a cone flying at the same Mach number have different flows surrounding them.
