Effects of Fluid Compressibility

The last in the six-video series makes extensive use of the analogy between gravity and sound waves and illustrates, through laboratory demonstrations and animation, the con cepts of wave celerity, shock waves and surges, wave reflec tion and water hammer. Two-dimensional waves are produced by flow past a point source at various speeds relative to the wave celerity to illus trate the effect of changing Mach number, and the principle is applied to flow at curved and abrupt wall deflections. Axisymmetric and three-dimensional wave patterns are then portrayed using color Schlieren pictures. http://iihr.uiowa.edu VIDEO TRANSCRIPT: http://www.iihr.uiowa.edu/research/pu...
