Single pressure atomized hollow cone nozzle and dual atomizer hollow cone nozzle design square hollow cone nozzle atomizer design the most critical is calculated , usually hollow cone nozzle calculation includes working two aspects: First, the requirements the hollow cone nozzle flow , spray angle , work pressure and fuel ( or liquid , etc. ) physical parameters , determine hollow cone nozzle geometry. The second is known

Under the geometric parameters and fluid properties premise parameters , calculate the amount of fuel spray cone angle , and the estimated atomization quality. The former is called hollow cone nozzle design calculations , which is called performance checking calculations. For hollow cone nozzle new design , both of which work should be carried out . For existing hollow cone nozzle , you can , after mapping, checking performance computing , and as a basis for improved modification of this procedure to the new design than hollow cone nozzles

More accurate and reliable design error is very small , the company is also frequently used method . In order to accurately calculate the design pressure of the atomizing single hollow cone nozzle and dual hollow cone nozzle atomization , the company conducted a lot of research , proposed a number of methods . Recently I am using the design method is based on the principle of maximum flow method and the momentum equation method . In addition we have many titles raw or improved methods based sauce on this basis .

????Abbondanza Rameau Abramovich former Soviet scholars put forward the principle of maximum flow method . No false been simplified : the late considering viscous oil , fuel flow path omitted

Velocity ; and that the flow is axisymmetric . Therefore, according to this method when calculating the flow coefficient u hollow cone nozzle and spray cone angle a, small viscous liquid ( such as water and gasoline ) , which approximate the ideal fluid and a large meteor main vents, reason perish not very different values ??and test values . The spray cone angle of high viscosity and low flow calculation is too large, the flow is too small . Because the effects of viscous fluid momentum mainly in the torque reduction and total pressure loss increases. In response to these problems, many researchers have proposed a correction method , which can be divided into pure empirical method and semi-empirical method. Experience pure law which have empirical coefficient method and empirical formula , which is based on a large number of experimental data , summarized or empirical correction factor correction formula for the flow coefficient and spray cone angle ( or structural characteristic coefficient ) can be reduced in engineering design design engineering, there are some practical value. The rule of thumb is based on semi- theoretical analysis to identify sticky mouth work on Sha

The impact of the introduction of a number of empirical coefficients , or the formula for calculating , or draw a graph of . The typical approach is to compare the former Soviet Union in Afghanistan 's Kelaqike based on the theory proposed , considering the swirl chamber wall and down to rotate the momentum of the fluid friction torque caused by the impact of reduced moments , substitute an equivalent geometric characteristics Ae ideal fluid of a, the ideal fluid characteristic curve can be calculated . Momentum equation method is considering moving factory viscous effects of the most tangential moments and total pressure on the introduction of the moment of momentum to keep the total pressure coefficient and the hollow cone nozzle

Loss coefficient ( including the impact of the loss into the oil channel swirl chamber wall friction losses and loss ) , and into the oil channel structure their size and Reynolds number Re , and therefore the calculation error is small , but it is more complicated to use .

????But in fact , the company uses the most calculating method is a calculation method to combine the principles of law and the maximum flow momentum equation method , in addition to improving the experience by making the calculation method coupled with hollow cone nozzle design is very reliable. Whichever method is used , but the design calculations, experience how rich, hollow cone nozzle design will exist error , must pass the test to adjust , but some differences debugging workload size , in order to shape the final design drawings hollow cone nozzle
