Abstract

Through outlet pipe with throttle, each gas tank is connected to jet orifice of smoke plume. Jet orifices of smoke plume of multiple gas tanks are arranged on vertical plane in sequence from top to low in same jetting direction. Through cut off valve, gas tank is connected to generation system of smoke plume in white color. Through adjustable valve of compressed air, each gas tank is connected to system of compressed air. Each gas tank is connected to color injection system. Electric throttle, electric cut off valve, and electric adjustable valve of compressed air are connected to intelligent control system electrically. The color injection system includes environment protective color smoke agent on base of gas tank, and connected color generation controller, which is connected to intelligent control system electrically. The invention discloses device of displaying environment protective vivid striking flow pattern of flow field in clear level of structure for wind tunnel test.

Description

technical field [0001] The patent of the present invention relates to a smoke flow device for wind tunnel test, especially a smoke flow device that can generate multiple colors to realize the vivid and eye-catching display of the flow field flow state of the tested piece in the wind tunnel, so that the tested piece can The flow state is more visually impactful. Background technique [0002] When conducting experimental research on the aerodynamic characteristics of a moving object, testers often conduct a smoke flow test on the specimen to conduct a qualitative analysis of the flow field flow state of the specimen, so as to determine the pros and cons of the aerodynamic characteristics of the moving object . At present, the smoke agent used in the wind tunnel smoke test is a white smoke produced by heating the resistance wire, which not only pollutes the test personnel, the wind tunnel, the wind tunnel equipment and the surrounding environment, but also after each test, To...
