    This paper is limited mainly to an analysis of the data presently available in the literaturc.Three topics have been investigated,namely, 1.the behavior of the resistance coefficient of an aerated flow, 2.the principal flow parameter for the correlation of data on air entrainment, and 3.the distribution of air concentration. According to Ehrenberger,the aerated flow in a channel consists of three zones of flow in addition to the zone of pure water that may possibly exist near the bed of the channel.These are the zone of air with water droplets,the zone of water with air bubbles,and a transition zone in between the foregoing two.In order to bring out more clearly the dynamical nature,of the flow,we propose,by analogy to sediment movement, to call the zones of air with water droplets and those of water with air bubbles respec- tively the zones of saltation and suspension. It was found that the channel inclination has a marked influence on the resistance coefficient of the flow(see fig.1).With the slope kept under a certain critical value (Straub and Anderson's data yield a critical inclination of about 30°),the Chezy co- efficient of the flow will remain the same as that of a flow without air entrainment. When the channel slope exceeds this critical value,however,an increase of the slope will cause the Chezy coefficient to increase accordingly.This is true over a certain range of Reynolds number.Beyond this range,increase in the Reynold's number will even- tually bring the Chezy coefficient back to its value for conventional water flow.An ex planation for the foregoing phenomenon has been given in the paper. Figures 2 to 4 indicate clearly that U/(g(1-)h_(99))~(1/2)is a principal flow parameter for the correlation of air-entrainment data.As this parameter is of the type of a Froude number,the foregoing statement implies that prototype phenomena of air entrainment may be reproduced in the laboratory.

    本文主要内容为根据前从资料探讨下列问题:1.掺气水流的阻力规律;2.控制掺气水流的基本参数;3.掺气浓度的断面分布。分析结果说明均匀掺气水流的阻力系数和底坡有着密切关系.这是清水水流所无的特异现象.已有资料的分析也说明 U/g~(1/2)是控制二元掺气水流的基本参数.在理论分析方面,我们提出了考虑质量脉动的概念,并提出了修改后的平均掺气分布微分方程式。

    The general equations of motion,mass conservation,continuity and energy are de- rived for the aerated turbulent water flow.The equations appear in the paper as Eqs.(6),(7),(8)and(12),where c denotes the air concentration and a_i the rise velo- city of air bubbles.Equation(6)differs significantly from the Reynolds equation by the appearance of the additional turbulent concentration stress The two-dimensional aerated steady uniform open channel flow is studied in detail, for which the stress equation(16)is first derived,making use of Eqs.(6),(7)and(8). It is pointed out that Eq.(16)contains the gravitational force gρ sin θ(y- which increases with the angle θ of inclination,and the concentration stresscos θ,which decreases with θ.As the velocity is influenced by these two quantities,the increase of discharge with θ should be less for the aerated open channel flow than for the nonaerated. As needed for subsequent analysis,the test values of against Y_1~′/d_s obtained from Straub and Anderson's data for the open channel flow are plotted in Figs.(5)and(6).The symbol d_s is the depth from the channel bed(y=0)to the interface(y=d_s)between the water and the air flow; and are the air concentra- tions at the bed and at the interface respectively is the corresponding sectional mean; Y_1~′ is the distance from the center of the entrained air mass to the interface. Following the two figures,the velocity-profile equations are derived by using Eq.(16) and Prandtl's mixing length(l)theory.The plane(y=d_1)of the maximum velocity is considered to divide the open channel flow into two regions:the lower region 0≤y≤d_1 near the bottom wall,and the upper region d_1≤y≤d_s near the interface, both having comparable depths.For the lower region,l=Ky is assumed as usual and a logarithmic velocity profile in the form of Eq.(24)is obtained,where u_1~* is the shear- stress velocity at y=d_1.In Eq.(23),which is used to define u_1~*,k is the ratio of - to gρ(y).For the upper region,however,the turbulence is con- sidered“free”,and the assumption l/d_s=D yields a linear velocity profile with adverse transverse gradient.As shown by Figs.7 and 8,measured velocities such as given by Straub and Lamb for different angles θ can be plotted in accordance with the two velocity equations. Using Eqs.(24)and(26),the resistance equation(30),which contains the universal constants A,K,B,D,k,d_1/d_s and /u_1~*,and expresses Chezy's C as a function of θ,Re,,is finally derived.

    The broad-band absorbers for anechoic tank have been developed. Vermiculite flakes were used as filler to increase the loss and to improve the compressibility of butyl rubber, a sound absorbing material with high loss was thus obtained. By adding air bubbles in vermiculite flakes, the bulk compressive strain in rubber is changed into shear strain. Therefore, the effective loss factor of material increases with increase of the volume ratio of the bubble.Rib structures with parallel channel with total lengths of 20 cm and 15 cm (transition part being 15 cm and 10 cm respectively) have been used for the purpose of economy of the testing material. The channel width is 3 cm The reflection coefficient is less than 10% in the frequency range of 5-80kHz.
