Integrated adjustable smoke tunnel fuming device

Abstract

The invention relates to an integrated adjustable smoke tunnel fuming device. The integrated adjustable smoke tunnel fuming device comprises a shell, and an evaporation unit and a tobacco tar storage and backflow unit which are arranged in the shell. According to the integrated adjustable smoke tunnel fuming device, the integrated design of concentrating air inlet, smoke generation and smoke exhaust is adopted, and a longitudinal discrete smoke supply mode is adopted, so that the problem that the smoke concentration is reduced due to the fact that a traditional smoke guide pipe type smoke generator supplies smoke in a concentrated mode through an external smoke generation device, and the distance between smoke passing pipelines is long is solved; the fuming process is concentrated, continuous and uniform; two-dimensional continuous smoke can be generated in a flow field by adopting the longitudinal discrete smoke supply mode, smoke lines in different states can be obtained by adjusting the longitudinal number, spacing and size of holes aligned to the smoke outlet through sliding and rotating the baffle embedded into the groove in the inner side of the smoke outlet according to test requirements, and the number, spacing and thickness of the smoke lines are not limited by the diameter of the pipeline, and the device has better applicability in a small low-speed wind tunnel.

Description

technical field [0001] The invention belongs to the field of wind tunnel experiments, and relates to a smoke generating device in a wind tunnel, in particular to an integrated adjustable smoke generating device in a wind tunnel. Background technique [0002] With the rapid development of the theoretical analysis and numerical calculation capabilities of fluid mechanics, the flow field display technology that can visually demonstrate and verify theoretical results is also becoming more and more important. Among the many flow field display technologies, smoke tunnel is one of the most basic methods, which has the advantages of simple principle, high degree of visualization, and stable effect. In the teaching and scientific research of fluid mechanics, the visualization of the flow field is often realized by means of smoke, and the smoke line generated by the smoke device shows the state of the flow field around the flow object. Therefore, the good smoke effect of the smoke ge...

AI Technical Summary

Problems solved by technology

[0005] To sum up, the existing smoke tunnel still lacks a smoke generating device that can generate smoke evenly and continuously, has little influence on the flow field of a small low-speed wind tunnel, and can adjust the state of the smoke line according to the test needs.
