  plate distance
Also, when the plate distance of the supporter from the cathode head within the reactor was 4 cm, the concentration gradients of C7H5F3 and SiH4 were the greatest.
      
The methodology is successful in providing quantitative information about the mineral area fraction, the mean plate distance or pore size and the intercept frequency as a function of angle.
      
The bases for comparison were mean plate thickness, mean plate distance, mineral area fraction, mineral volume fraction and plate orientation coupled with mechanical tests.
      
Experimental parameters were in the Reynolds number range 9200-73500, and in?the nozzle-to-plate distance range 2-10.
      
Following this, the cone-and-plate distance method, which was introduced by Jackson and Kaye, is discussed.

The construction and working principle of inclined parallel plate settler were introduced. The feed throughput related to the plate distance and the properties of system were analyzed.The result of experiments shows that the inclined plate settlers have a high throughput per unit area and the degree of separation compared with common gravity settler.For the given size of dispersion band,the plate distance has an optimum solution which depends on the properties of system, working condition...

在介绍斜板沉降器结构及操作特性的基础上,分析了处理负荷与结构尺寸、体系物性的关系.通过实验研究了斜板沉降器板间距对处理负荷的影响.结果表明,斜板沉降器的处理负荷与同尺寸的普通重力沉降器相比有大幅度的提高.对于一定的分散带厚度,板间距与处理负荷间存在着最宜设计,该最宜设计值取决于物系性质、操作条件及两相比率

The characteristics of the far-field noise of impinging jet with 3-millimeter diameter axisymmetric convergent nozzle under the condition of variable nozzle-to-plate distance,and their methanism were investigated experimentally.It is found that the far-field noise intensity of the 3 mm nozzle impinging jet has a saw-tooth behavior with the variation of nozzle-to-plate distance,and there are some chunky broadband peaks on the narrow-band noise spectrum,and these peaks exist only on the upstream of...

The characteristics of the far-field noise of impinging jet with 3-millimeter diameter axisymmetric convergent nozzle under the condition of variable nozzle-to-plate distance,and their methanism were investigated experimentally.It is found that the far-field noise intensity of the 3 mm nozzle impinging jet has a saw-tooth behavior with the variation of nozzle-to-plate distance,and there are some chunky broadband peaks on the narrow-band noise spectrum,and these peaks exist only on the upstream of the jet.According to the consideration of key factors responsible for the feedback loop and results of the experiments performed to detect the effect of nozzle exit lip thickness on these new phenomena,the feedback mechanism is suggested to be responsible for these phenomena,and the associated noise is defined as weak feedback noise.The interaction of the turbulent noise and weak feedback noise induces the saw-tooth behavior of the total noise intensity with the variation of nozzle-to-plate distance.

测量了 3毫米口径轴对称收缩喷嘴射流冲击大平板产生的噪声随冲击距离变化的特性。发现远场噪声随冲击距离的变化呈锯齿状 ,射流上游的噪声频谱上有粗缓、跨较宽频带的尖峰。根据不同唇厚喷嘴的实验对比 ,判断这些现象跟反馈有关 ,称为反馈噪声 ,而且正是反馈噪声与湍流噪声的相互作用 ,导致这种锯齿现象和射流上游的宽频尖峰

In the study of flow oscillation and discrete frequency noise of impinging jet, it is found that there is a critical pressure ratio for a given nozzle and a nozzle-to-plate distance. When the pressure ratio of a nozzle is higher than the critical ratio value, the flow oscillations and the associated discrete noise are significatly suppressed or even cease. Mechanism of this critical pressure ratio is explained by the explanation that acoustic feedback and receptivity diminish at high levels of under-expansion....

In the study of flow oscillation and discrete frequency noise of impinging jet, it is found that there is a critical pressure ratio for a given nozzle and a nozzle-to-plate distance. When the pressure ratio of a nozzle is higher than the critical ratio value, the flow oscillations and the associated discrete noise are significatly suppressed or even cease. Mechanism of this critical pressure ratio is explained by the explanation that acoustic feedback and receptivity diminish at high levels of under-expansion. The feedback loop and associated discrete noise of oblique impinging jet are studied experimentally for the first time and the critical pressure ratio value is believed to be dependent on the distance between the nozzle and plate and impinging angle. The experimental results indicate that the critical pressure ratio value increases with the nozzle-to-plate distance, and decreases with the jet impinging obliquity.

为探索冲击射流离散频率噪声的产生机理 ,系统地研究了冲击射流离散频率噪声的特性。发现对于给定的喷嘴和冲击距离 ,存在一个压比临界点 ,当压比高于此临界点值时 ,流场振荡和离散频率噪声被显著抑制乃至消失。解释了此压比临界值的机理 :气流的出口膨胀阻遏了反馈声波对喷嘴唇口的激发 ,从而抑制了反馈环的形成。研究了射流倾斜冲击平板时反馈环以及相应的离散频率噪声 ,推测此压比临界点值与冲击距离、射流倾斜角度有关。实验表明 :压比临界点值随冲击距离在一定范围内的增加而增高 ,随喷嘴偏离垂直角度增加而减低。
