某二维水翼空化数值模型对比

以二维水翼计算模型为研究对象，采用数值模拟的方法，通过不同的空化模型和湍流模型对计算模型进行数值模拟研究，得到了翼型在空化过程中空泡的运动规律。结果表明：该翼型在不同空化模型下，发生空化时，空化过程包含了空泡的产生、发展、脱落和溃灭几个过程，空化的运动过程总具有明显的周期性；Schnerr-Sauer模型的计算结果与实际的水翼空化流动过程相吻合，Schnerr-Sauer空化模型可以很好地模拟绕水翼的空化流动过程。 We took a two-dimensional hydrofoil calculation model as the research object, and adopted the method of numerical simulation. The movement of the hydrofoil cavity in the cavitation process was obtained through the numerical simulation study on different cavitation models and turbulence models. The result showed: In different types of cavitation models, the cavitation process of this hydrofoil included the generation, development, fall-off, and burst of vacuoles, and the process showed obvious periodicity. The simulation result of S-S cavitation model was consistent with the actual movement. The S-S cavitation model can well simulate the flow around a hydrofoil in the cavitation process.
