The paper begins with a theoretical analysis of potential flow for the two-di- mensional conduit inlet,and after the boundary curve of constant pressure is obtained, it is transformed to the case of axial symmetry.It is hoped that the pressure along the new boundary,be nearly constant.The method of transformation is mainly that for equal distance ratios(i.e.,distance divided by entrance width in the two-dimen- sional case and that divided by entrance diameter in the axially symmetrical case), area ratios(i.e.sectional...

The paper begins with a theoretical analysis of potential flow for the two-di- mensional conduit inlet,and after the boundary curve of constant pressure is obtained, it is transformed to the case of axial symmetry.It is hoped that the pressure along the new boundary,be nearly constant.The method of transformation is mainly that for equal distance ratios(i.e.,distance divided by entrance width in the two-dimen- sional case and that divided by entrance diameter in the axially symmetrical case), area ratios(i.e.sectional area divided by entrance area in both cases)are equal. The pressure distribution along the curved wall of an axially symmetric inlet so obtained was calculated by the relaxation method,and that of another was measured from an air-flow model test.The results as given in Figures 10 and 13 of the paper show that although the pressure along the wall is not constant,the variation is not great.The paper finally suggests that as for to reduce the possibility of cavitation, the forms of the axially symmetric inlets given by Equations(5)and(6)of the paper may be considered as adequate for practical cngineering use,with the restriction that the value of k which appears in the two equations not be greater than 0.05,in order to prevent the possible separation of flow from the inlet wall.

文中给出了隧洞进水口曲线为等压的二元分析结果,然后将此二元进水口的曲线形式转变为轴对称进水口的曲面形式。所用的转变方法是:当 x/D=(x_1)/B时,d/D=(b/B)~(1/2),其中 d、x和 D 分别为轴对称进水口段中某断面的直径,由起始断面至该断面的距离和起始断面的直径;b、x 和 B 分别为相应二元情形的某断面的宽度,由起始断面至该断面的距离和起始断面的宽度。对用这种方法得到的一个轴对称进水口曲面上压力分布,进行了松弛法计算,还对另一个进行了气流模型试验。结果如文中图10及图13指明,曲面上压力虽然不是等值的,但变化不大。文中建议,就减蚀的意义而言,式(5)和式(6)所给轴对称进水口曲面的形式是可以考虑来作为实际工程上应用的,但为了避免可能发生水流从边壁上脱离的现象,式中 k 值应取小于或等于0.05。

Modulation of air stream is an efficient method of sound production. Man's speech organs, sirens, electro-pneumatic loudspeakers as well as common whistles are all based on this principle. The features of air stream sound sources are their high efficiency and possibility of high power outputs, which afford them practical value. The sound production by modulating air streams were discussed by previous authors and theories-given, but some were oversimplified and others too involved to allow practical computations....

Modulation of air stream is an efficient method of sound production. Man's speech organs, sirens, electro-pneumatic loudspeakers as well as common whistles are all based on this principle. The features of air stream sound sources are their high efficiency and possibility of high power outputs, which afford them practical value. The sound production by modulating air streams were discussed by previous authors and theories-given, but some were oversimplified and others too involved to allow practical computations. In this paper, air flow vs pressure characteristics of air stream sources are derived from the basic theory of gasdynamics and graphical method is presented for the estimation of sound radiation under given conditions of plenum pressure and nozzle-to-horn throat area ratio. It is established that although the air flow characteristics as well as the radiation relations are nonlinear, the radiated sound power is determined mainly by the radiation of the fundamental, and approximations give rise to simple expressions for the radiated sound power, the air stream yield and efficiency, with an error less than 1 dB from exact results. Charts are given to facilitate design and question of optimum condition is discussed.

利用气流调制以产生声音是一个比较有效的方法。人的发声器官、旋笛、电动气流扬声器以及一般哨子等都是根据这个原理。气流声源的特点是效率高,功率可以很大,有实用价值。关于气流声源的发声原理,过去已有一些讨论,但有的是过分简化,有的比较细致,但又过于繁复,不便计算。本文从气体动力学的基本原理出发,求得气流声源的气流-压力特性,并用图解法求得在给定气室压力和气流喷口面积比的条件下声辐射特性的方法,考虑到气流声源的气流特性和辐射关系都是非线性的,但是辐射声功率主要由基频决定,从而用近似理论求得了声功率、气流产额和气流效率的简单表达式,和严格理论的结果相比,误差不到1分贝。文中把结果画成图表以便计算,并讨论了最佳设计的问题。

Recently a JDC three bladed cpp series with expanded area ratio 0.35,0.50 and 0.65 was developed in the ship model towing tank of Shanghai Chiao-Tung University. The open water experimental results of the JDC 3-50 series are presented in this paper. All the experimental data are analyzed by the regression method in the DJS-6 digital computer. The polynomial coefficients, open water characteristic curves, Bp-δ digram and the hydrodynamical spindle torque curves are given. For practical design purposes a simplified design chart and the calculated centrifugal spindle torque coefficients at the initial pitch ratios are also given.Compared with some foreign propeller series, it shows that the open water characteristics of the JUC 3-50 series are satisfactory.
