Electrogasdynamic spectral anemometer
专利汇可以提供Electrogasdynamic spectral anemometer专利检索，专利查询，专利分析的服务。并且An electrogasdynamic spectral anemometer including a particle injector and a particle collector that are inserted into a turbulent fluid stream that is under investigation. The injector includes a hollow cylinder into which near saturated steam from an outside source is introduced. The injector also includes a nozzle, a corona needle and an attractor ring which are oppositely charged and located within the nozzle. As the steam passes through the nozzle it supersaturates and condenses into droplets having a size that is primarily determined by the condition of the incoming steam. The droplets are then charged through the corona developed between the corona needle and the attractor ring. Then the charged droplets are ejected from the nozzle and into the stream to be measured where they follow its rapid fluctuations. These charged particles move towards the collector which may be placed downstream of the injector. When a charged particle passes the collector it becomes neutralized and transmits an electrical signal into collector circuitry where it is analyzed to provide information about the intensity of the turbulence at various frequencies. Different droplet sizes are used for different turbulent frequencies of interest depending on the maximum value of the frequency present in the flow.，下面是Electrogasdynamic spectral anemometer专利的具体信息内容。
