Example 5 The radial-flow turbine illustrated in Figure 5.15 may be analyzed with the aid of the moment-of-momentum expression. In this device, the fluid (usually water) enters the guide vanes, which impart a tangential velocity and hence angular momentum to the fluid before it enters the revolving runner, which reduces the angular momentum of the fluid while delivering torque to the runner. Figure 5.15 Radial-flow turbine. The control volume to be used is illustrated below in Figure 5.16. The outer boundary of the control volume is at radius rį, and the inner boundary is at r2. The width of the runner is h. -h- U1 Figure 5.16 Radial-flow turbine-runner control volume.
