Industrial hollow cone nozzle and nozzle

Experimental study of cavitation nozzle overview so far , scientific and technical personnel have launched a considerable number of experimental observations to analyze the characteristics of cavitation inside the nozzle . Due to the long-term unremitting efforts , the experimental research on cone nozzle cavitation mainly made ??significant progress in two areas: First , make sure the nozzle cavitation flow in the macro-structure of quasi- steady-state conditions and the factors that affect it ; second , confirmed that the cavitation process on the nozzle flow characteristics ( ie, flow coefficient ) were studied. The following lists the main conclusions of the study . Process and mechanism of the impact of diesel fuel atomization nozzle jet instability cavitation cavitation shaped display

Hydraulic reflux state recognized as early as 1959 , Bergwerk model diesel transparent cone nozzles and hydraulic cavitation process reflux (hydraulic flip, the gas is forced into the hole of the outer jet , and occupies a region near the wall cavity phenomenon ) were observed and found that with decreasing size of the nozzle experiment is difficult to see water back.

Meanwhile , Bergwerk strive to associate with Reynolds hydraulic backflow occurs , but to no avail . Soteriou enlarged model , who use the hydraulic nozzle reflux key observation , and that the actual diesel injection process, due to the small size of the injection hole and the injection transient conditions , the occurrence of water is refluxed . Laoonual , who used to enlarge the size of the VCO (valve covered orifice) conical nozzle experimental observations , and found that when the aspect ratio of greater than 10 orifice or orifice entrance grind out the possibility of very low hydraulic reflux occurs when the fillet . Ultra cavitation Chaves , who used diesel nozzle size and the actual size of the nozzle considerable experimental model , the degree of concurrency now cavitation under certain conditions of back pressure jet spray hole with elevated pressure and increased when the injection pressure is increased to a certain when the extent of cavitation orifice area would have been extended to the formation of ultra- orifice outlet (supercavitation

) .

Badock , who also uses the true size of the nozzle to do experiments , they found that at high injection pressure ( ultra cavitation ) conditions orifice center still has full plume exists. It is noted that , and found no water and refluxed Badock et al Chaves et experiments. Line cavitation Afzal et al , Roth et al and Gavaises & Andriotis observation enlarge the size of the nozzle to form an unstable cavitation , which they named the line cavitation (string cavitation). Line cavitation generally occurs at the inlet orifice upstream of the recirculation zone , and its essence is the vortex motion induced cavitation . Andriotis et al lines cavitation phenomena more detailed analysis , sought to line up the probability of occurrence of cavitation and associated Strouhal number appears in the specific location and needle lift , cavitation number , Reynolds number and swirl , but not very successful. So far , the internal space of a diesel nozzle for experimental observation of enlarged mainly in the size of the model for industrial nozzles . However, due to the presence of foot than the effects of cavitation nozzle in the form of large size may not appear in the actual size of the diesel fuel nozzle , such as hydraulic return, line cavitation , both need further confirmation.
