The model design parameters are found by solving analytically using governing isentropic flow relations (1) (2) (3), oblique shock wave relations (4) (5) by following the shock-on-lip condition.
Oblique shock waves, expansion waves and shock wave interactions are mainly considered.
Scramjet inlet incorporates oblique shock waves in various external and internal blends in order to achieve the desired combinations of compression and turning.
The inlet is designed in such a way that the oblique shock waves impinges at the cowl tip thereby increasing the mass flow rate (shock-on-lip condition).
26 m, a strong oblique shock wave train is formed, which may be caused by a great amount of heat release in this location and the oblique shock wave/boundary layer interaction.
There is also an oblique shock wave that starts from the leading edge of the cavity.
2 m corresponds to the location where the oblique shock wave strongly interacted with boundary layer, which can be seen in Figure 6(a).
Before attempting a full-scale blast load analysis, the engineers conducted three analyses to verify the Abaqus CEL could simulate normal and oblique shock wave
reflections against the Lagrangian model accurately.
The oblique shock wave formed over the concave corner of the ramp is shown in fig.
The strong disturbances cleave into an oblique shock wave to the free stream and oblique shock is stronger than the Mach wave (i.
The changes across the oblique shock wave are severe as p increases, the larger value of P will have the strong shock solution and the smaller value of p will have the weak shock solution.
If the exit pressure is slightly less than the back pressure, then oblique shock waves
occur at the nozzle exit as shown in figure 2.
