【摘要】 为了研究各种因素,如水的空气含量、流速、表面粗糙以及气核对各种空泡初生的影响,在上海交通大学空泡水筒进行了国际拖曳水池会议推荐的水翼—头体组合体的试验。本文提供了试验程序和试验结果,并与其他单位的同样试验作了比较。试验结果表明各种空泡初生都受上述因素的影响,而且影响程度随空泡类型而不同。与其他单位试验结果比较,发观相互间都存在很大差异。这些差异,除了由于试验设备不同外,可能是由于对各种空泡初生缺乏统一的定义,试验技术和程序的不同等而引起的。根据十六届国际拖曳水池会议空泡委员会的要求,部分试验结果己提交该委员会并在十六届国际拖曳水池会议录空泡委员会的报告中引用。更多还原

【Abstract】 In order to investigate the different factors, such as air content in water, flowvelocity,surface roughness and gas nucleus,effecting the inception of various cavita-tions, an ITTC foil-headform combination was tested in the cavitation tunnel ofShanghai Jiao Tong University. In this paper, the test procedures and results are presented and compared withresults of similar tests obtained by other establishments.The test results show that theinception of various cavitation is effected by the factors mentioned above and that thedegree of influence is dependent on the different types of cavitation.Comparisons ofthese results with those obtained by other establishments revealed much discrepanciesamong them.Except for the difference in testing facilities,these discrepancies may beexplained by tl e lack of a unified definition of various cavitation inception,the dif-ference of test techniques and procedures,and so on. By recommandation of the Cavitation Committee of the 16th ITTC,some of theresults have been delivered to the Committee and referred to in the Proceedings of the16th ITTC.更多还原
