采用这种送风方式，工作区处于射流区，不产生死区，可实现主厂房“串联式”通风。 - First , a simple discussion for the mechanism about electrostatic atomization of the liquids has been given ; then the paper theoretically analyzed waving course , liquid drop producing course , and the liquid drop diffusing course in electrostatics atomization process . , gave an analysis about the methods about carrying charges to the liquid drop , and analyzed that liquid with high electrical conductivity can be carried charges and atomized by electric field , while the isolated liquid with low electrical conductivity can be charged fully with the soakage electrode and inducing charge methods . at last the paper designed and configured the experimental equipment , conducted the atomization experiment to the three liquid medium - kerosene , emulsifier and alcohol under the same environment , handled the experimental results , then summarized the relationship between liquid electrostatic atomization effect and liquid surface tension , electronic conductivity and viscosity , along with the influence of voltage to electrostatic atomization and so on , found out the liquid atomization rule in high voltage electrostatic field
首先,对液体介质的静电雾化机理作了初步的探讨,理论上分析了液体雾化过程中射流区、波纹区、雾滴区和雾滴扩散区;然后对液体荷电方法进行了研究分析,对于高电导率的液体,场致荷电和接触荷电可以使其雾化,而对于电导率较低的绝缘液体,需用浸润电极荷电和感应荷电方法使其充分带电;最后,根据前面的研究分析,设计和组装试验装置,在同一环境下对煤油、乳化剂、酒精三种不同液体介质进行高压静电雾化试验,并对试验结果进行分析处理,总结出液体静电雾化与液体表面张力、电导率和粘度的关系及电压对液体静电雾化的影响等,得出高压静电场中液体雾化的一般规律。 - It is found that , the heat transfer coefficients in the area after at stagnation point is higher than that of common jetting although the heat transfer coefficients are smaller at stagnation point , and , comparing to common jetting , rotary jetting contributes to the even distribution of heat transfer coefficients near stagnation point
结果表明，尽管旋转射流的努谢尔特数在驻点附近低于普通射流的努谢尔特数，但在壁面射流区高于普通射流的努谢尔特数。与普通射流相比，旋转射流导致驻点附近区域的换热特性趋于均匀化。
