| Research Abstract |
Toward the quantitative prediction of cavitation instabilities in turbopumps, detailed measurements of cavitating flow in simplified models, namely two-dimensional cascade and isolated hydrofoils, are carried out in addition to high-speed video camera observations. From the combined data, unique characteristics of cavitating flow are extracted, and detailed flow data are presented. Numerical simulations are also carried out, and the numerical model required for the qualitative prediction of cavitating flow is discussed through the comparisons with the experiments.
