WebFeb 22, 2024 · The shock standoff distance found by this relation is compared with the numerical solutions obtained by solving the two-dimensional inviscid Euler equations, and with previous experimental …

WebInstead, a detached shock forms ahead of the concave corner. Such a detached shock is in fact the same as a bow shock discussed earlier. 2. If θ < θmax, two distinct oblique shocks with two different β angles are physically possible. The smaller β case is called a weak shock, and is the one most likely to occur in a typical supersonic flow. WebIn general the stationary detached shock wave is curved and thus the flow back of the shock is rotational. The effect of rotational flow upon the velocity and pressure …
