The spacing between the plates is sufficiently large that the flow does not choke and supersonic flow is maintained between them.
22.
The flow in a real exhaust port can easily be sonic with choked flow occurring and even supersonic flow in areas.
23.
The major difficulty with the acoustic analogy, however, is that the sound source is not compact in supersonic flow.
24.
"' Isentropic expansion "'waves are created when a supersonic flow is redirected along a curved surface.
25.
Supersonic flow jumps over it by means of ramps, while subsonic flow is able to turn and exit through the gap.
26.
Thus the matter initially slows down, typically through a shock transition, and then accelerates again to become a supersonic flow.
27.
Usually with supersonic flow a positive pressure shock wave is generated at the front and a negative pressure shock wave at the rear.
28.
Transonic and supersonic flows are compressible, and neglecting the changes in density in these flow fields will yield inaccurate results when performing calculations.
29.
The full potential equation is valid for supersonic flow at arbitrary angle of attack, as long as the assumption of irrotationality is applicable.
30.
His first publications came from Sauer's interests dealing with supersonic flow and precision problems of digital computations for numerical calculations of Eigenvalues.
