System technical field.
Background technique
During aviation aerospace engine design and use, it will usually face thermoacoustic instability problem.Thermoacoustic is unstable
Phenomenon is to be intercoupled, amplified with sound wave due to unstable heat release, so that a kind of wild effect generated, is related to flowing
The various aspects such as body, burning, heat transfer, acoustics betide in various power devices, serious destructive and strong noise,
The further investigation of various aspects is caused.
1859, the silk screen of heat was placed on a both ends open and erects pipeline (i.e. combustion chamber) lower half of placement by Rijke
Just there are very strong sound oscillation outflow in some partial position, pipeline the inside at once.Air exists in the slow flowing of pipeline
Compression and expansion two states.If providing heat to it when compression, heat is externally discharged when expansion, then
The state of compression and release will constantly be reinforced, and sonication will generate.This is typically due to heat, sound, fluid phase interaction
The unstable sounding caused by.Therefore, Rijke pipe becomes a succinct experimental provision of research thermoacoustic wild effect.
Researcher is managed in Rijke it was found that, vibrating the power of sound wave generation, and meeting changes with heat source position and become
Change.The position for efficiently and accurately changing heat source influences research heat source position to caused by engine operation result, plays
Vital effect.Rijke pipe is slender type, is hot environment during work, and researcher's inconvenience enters inside Rijke pipe
Heat source position is adjusted.When using heated filament net as heat source, the mode for generalling use dragging adjusts heat source position, this
Mode is inflexible, accurate, has larger impact to experimental result accuracy.
It is promoted in research field in aviation aerospace, researcher utilizes burner more, by fuel gas in pipeline internal point
The mode that combustion generates heat is tested.Traditional appendix supplied to burner, mostly uses greatly folding mode, realizes heat source
Length, position are adjustable.But folding mode operation is taken to need very large space that can just complete, in the experiment of Rijke pipe,
Its combustion chamber is slender type, and space is limited, and this mode has been not suitable for, and cannot complete heat source position and flexibly, accurately adjust.
Summary of the invention
Mesh of the invention is in order to overcome the drawbacks of the prior art, in order to solve to be tied in the experiment of Rijke pipe by combustion chamber
Conformational space limitation, can not effectively adjust burner steam line length and position, lead to not that asking for heat source position is adjusted flexibly
Topic, proposes a kind of scalable steam line for slender type combustion chamber.Using the present invention, can in a limited space in it is long away from
From conveying gas, and duct length and position can be adjusted continuous, automatically and arbitrarily, so that heat source position be adjusted flexibly.
