三角形突体初生空化与空蚀的试验研究

通过不同高度与不同边坡组合的等腰三角形实体初生空化试验和突体后水泥砂浆材料的初生空蚀试验．量测了初生空化数、初生空蚀数和空蚀麻点率．并预测了５０ｍ／ｓ。流速级时初生空化数和砂浆表面出现麻点的初生空蚀教．得到的预测值与已有的原型观测值比较，基本一致，为拟定相应的不平整度控制标准提供了依据。

Study of the Incipient Cavitation and Erosion on Surface Triangular Protrusions

Through the hydraulic model experiments on both inception of cavitation and erosion on isolated surface triangular protrusion to be composed of different height and side slope.that are made from cement mortar.we measure the cavitation number and the erosion damage pitting relative to these experiments.The erosion damage,which the velocity of water flow is near 50m/s,are estimated when pitting appear on surface of the cement mortar.The results of experimentally are found good agreement with actual engineering results at home and abroad.and it can not only be wide used for hydraulic project design and constraction.but also provide a numberical basis for ftrther research of control standard an solid wall surface irregularizes.
