Simulation of Cavitation Water Flows

Figure 7

Computer experiments at a cavitation number of in a duct. (a) A top view of the instantaneous configuration of bubbles in a cavitating water flow of water through a pipe with inner diameter of  m at the discharge of  L/s and at the cavitation number of . (b) A view from below of the bubbles in the cavitating flow of water through the pipe. Here, the large cavities consisting of small individual bubbles are illustrated. (c) Computed contours of the averaged vapor volume fraction on the xz-plane for the cavitating water flow in (a). Here, a color code as illustrated below the stones is used to indicate the values of the averaged vapor volume fraction on the surfaces of the stones. (d)–(g) Variations of as a function of at the sampling ports 1 through 16, respectively.
