Abstract
The degree of thermodynamic effect on inducer cavitation was discussed based on the non-dimensional thermodynamic parameter τ/τ_T. We attempted to relate the depression of cavitation number Δσ to the thermodynamic parameter τ/τ_T through the previous experiment. It was found that the depression of cavitation number Δσ increases as increasing the thermodynamic parameter τ/τ_T with rotational speed and temperature.
