Fig. 20 Measurement of
prehydraulic jump angle
Angle measurement line
Two phase boundary
Figure 20 shows the method to measure the prehydraulic jump angle near the
ramp area. The angle measures start from the lowest point of two-phase boundary
after the ramp, and measure the angle between the tangent line of two-phase
boundary and the horizontal line. Figure 21 shows a close-up view of the ramp
