The performance of the hydraulic turbine is shown in Figures 45 and 46. The first figure shows the overall head drop coefficient and efficiency vs. flow coefficient. The torque was calculated from the inducer and shroud torque shown on Figures 31, 35, and 38. The head drop coefficients on Figure 46 show large variations between hub and tip. Almost all of this variation is caused by the turbine inlet head distribution since the turbine head distribution was nearly constant from hub to tip. The design head drop was less than that actually measured by 14%, most likely due to the non-uniform inlet condition, shown appears to likely caused by previously. 7. which caused higher turbine inlet losses. The efficiency be invalid below a flow coefficient of 0.25. This is most the Keil probe measurements at off-design flow, as discussed Overall Performance The overall performance is defined as the head rise from inducer suction to hydraulic turbine discharge, since this represents the available head to the doenstream main stage (see Figure 2 for component location). Figure 47 shows the speed ratio and discharge head coefficients (from suction) for each blade row, inducer, rotor, and hydraulic turbine, based on the rotor tip velocity. The design values are also shown for comparison with the test data. The speed ratio is constant within 6% of the design value over the entire flow range tested. The efficiency and normalized input torque for the overall machine is shown in Figure 48. The overall efficiency of 40% at the design compares to 30% predicted overall efficiency of a part flow hydraulic turbine driven inducer which was designed for nearly the same operating conditions. The input torque represents the torque necessary to drive the boost pump, and would be added to the main pump torque in determining the total pump drive requirements. B. STEADY-STATE CAVITATING The steady-state cavitating tests were conducted at constant flow coefficient, with the suction pressure decreased from l:he non-cavitating con- dition, until at least 10% head loss was measured. The drive mode was an electric motor capable of maintaining constant speed to within + 0.1%. All cavitation testing was conducted with water temperature at 160°F (345°K) except for one test on the hubless inducer. The difference in available thermodynamic head between ambient temperature water and water at 160°F (345°K) is insignificant, per Ref 21; therefore, no attempt was made to normalize the data to standard water temperature. The head coefficient for the inducer cavitation performance was obtained from the Kiel probes rather than from static taps in the discharge line. During cavitation the Kiel probes gave erratic readings and were there- fore not used. Consequently, the head coefficients obtained from the cavitation curves will not agree with the head coefficients previously shown. The relative head coefficient value, however, is adequate to determine the per- centage head loss. 64PDF Image | HUBLESS INDUCER FLOW HYDRAULIC TURBINE INDUCER BOOST PUMP
