WebFeb 15, 2012 · Prandtl-Meyer expansion wave solver. This program solves the Prandtl-Meyer expansion wave problem by using the MacCormack's predictor-corrector technique, as described in the book "Computational fluid dynamics: the basics with applications" from J.D.Anderson. As a result, this code might be useful for those trying to solve the problem, … WebWhat is shock expansion theory? Shock-Expansion Theory. The combination of oblique-shock relations and Prandtl-Meyer wave relations constitutes Shock-Expansion Theory, which can be used to determine the flow properties and forces for simple 2-D shapes in supersonic flow. Flat-plate supersonic airfoil A flat plate is the simplest supersonic airfoil.

WebJun 1, 2014 · If the Prandtl–Meyer expansion wave is too strong, then the curvilinear shock degenerates into one more weak discontinuity inside the expansion fan (Fig. 1 a). The discontinuity τ 2 does not exist there, and non-interacted part r 4 of the wave r 1 serves instead of the shock j 4 which comes through the expansion fan otherwise. galvanized razor wire fence https://dreamsvacationtours.net

WebIn this example, as shown in Figure 5.53, the oncoming supersonic air flow undergoes an expansion wave (Prandtl–Meyer) on the top side (suction surface) of the flat plate and a compression wave (oblique shock) on the bottom side (pressure surface). The angle of attack equals the turning angle for the oblique shock. WebApr 14, 2024 · Therefore, we apply the method first proposed in , and the shape of the reflected shock is determined based on the condition of flow direction conjugation (i.e., the flow angles behind each point of the reflected shock j 2 and at the corresponding points of the Prandtl–Meyer expansion wave 2 must coincide).
