Test device for wind tunnel color smoke flow

Abstract

The invention discloses a wind tunnel colored smoke flow test device. Each gas storage tank (6) is connected with a smoke flow injection port (2) through an air outlet pipe with a throttle valve, and the smoke from a plurality of gas storage tanks (6) The flow injection ports (2) are arranged in a row on the vertical plane in accordance with the order of height and injection direction, and the gas storage tank (6) is connected with the white smoke generation system (9) through the stop valve, and each gas storage tank (6) Each air storage tank (6) communicates with the color injection system through the compressed air regulating valve to communicate with the compressed air system (10). The electric throttle valve (3), the electric stop valve (8), and the electric compressed air regulating valve (7) are electrically connected with the intelligent control system. The color injection system is an environment-friendly color fuming agent (12) arranged at the bottom of the gas storage tank (6) and a color generation controller (11) connected thereto. The color generating controller (11) is electrically connected with the intelligent control system. The invention provides an environment-friendly, vivid and eye-catching flow field display device with clear layers for wind tunnel tests.

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...
