Embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, plume storage distribution system is made up of four gas-holder 6, each gas-holder 6 is communicated with fume injecting orifice 2 by the escape pipe of tool electric throttle valve 3, escape pipe is for to realize adjustable for height escape pipe by draw-tube 4 moving up and down in outlet 5, the fume injecting orifice 2 of a plurality of gas-holder 6 is complied be arranged in a row consistent with injection direction of height order on vertical plane, each gas-holder 6 is connected with white plume generation systems 9 by electric check valve 8, each gas-holder 6 is communicated with compressed air system 10 by electronic compressed air regulating valve 7, be provided with environment-protecting color smoke agent 12 in the bottom of gas-holder 6, environment-protecting color smoke agent 12 is connected with color generator controller 11, electric throttle valve 3, electric check valve 8, electronic compressed air regulating valve 7 is electrically connected with intelligence control system, and color generator controller 11 is electrically connected with intelligence control system.
Referring to Fig. 1, Fig. 2 and Fig. 3, the white environmental protection plume that produces from white plume generation systems 9 can be divided into four the tunnel, and electric check valve 8 all is equipped with to realize independent control in each road, enters the gas-holder 6 in the plume storage distribution system; After entering the gas-holder 6 of plume distribution system from the environment-protecting color plume of color injected system 9, each environment-protecting color plume uses in the time of all can mixing and be stored in respectively in the gas-holder 6 in the plume storage distribution system in order to test uniformly with the white plume that comes from white plume system 9.If will control the electric check valve 8 of white plume closes, so, the environmental protection plume of being stored in the gas-holder 6 of plume storage distribution system then is the pure color smoke flow from environment-protecting color smoke agent 12, therefore, the control of the plume color density during test realizes by inject environmental protection white plume in the environment-protecting color plume.Being stored at four kinds of color smoke flows in the gas-holder 6 of plume storage distribution system respectively guides to the environment-protecting color plume by four escape pipes that insert four gas-holder 6 in the plume distribution system respectively wind-tunnel and is used during in order to test by the position of test specimen 1.The pressurized air that comes from compressed air system 10 is divided into four tunnel four gas-holder 6 that enter in the plume storage distribution system, and each road pressurized air all realizes entering the control that plume is stored compressed-air actuated flow and flow velocity in the gas-holder 6 in the distribution system with a compressed air regulating valve 7.In addition, control compressed-air actuated four compressed air regulating valves 7 and can also realize the automatic and passive injection of fume injecting orifice place plume: when four throttling valve of compressed-air actuated four compressed air regulating valve 7 Close Alls of control and the jet velocity of regulating fume injecting orifice 2 are in opening, be stored at environmental protection plume in the plume storage distribution system and will enter the position that escape pipe arrives fume injecting orifice 2 owing to self pressure, and this moment, because the test air-flow in the wind-tunnel has certain speed, the plume that comes out from fume injecting orifice 2 will obtain the speed identical with tunnel airstream and arrive test specimen 1, thereby realize the demonstration of test specimen 1 flow field fluidised form; When compressed-air actuated four compressed air regulating valves 7 of control are in opening, the environment-protecting color plume that is stored in the plume storage distribution system will obtain higher pressure, and by escape pipe arrival fume injecting orifice 2, automatically spray with certain speed, its spouting velocity can realize by the control of 0 meter per second to 30 meter per seconds by the electric throttle valve 3 that is loaded on fume injecting orifice 2 front portions.It is to realize by draw-tube 4 moving up and down in outlet 5 that the height and position of fume injecting orifice 2 is regulated.The generation of color smoke flow is by the bottom of the gas-holder 6 in plume storage distribution system pack into special-purpose environment-protecting color smoke agent 12 and (the remote-controlled control) that realizes by color generator controller 11.For wind tunnel test provides a kind of environmental protection, lively eye-catching, well-bedded flow field fluidised form display device.
