【Abstract】 For the complexity of efficiency similitude of prototype hydraulic turbines, so far there is actually not a consistent formula in many applied ones. After a brief summary to current states, an efficiency similitude formula of prototype hydraulic turbines used for changeable behavior is advanced based on the principle of similitude and the constituent analysis of hydraulic losses. The comparison between this and previous typical formulae in four field examples is shown too.更多还原
