Background technology
It is to inject in the subsonic speed section of nozzle throat upstream that current common Investigation on Supersonic Coil device (COIL) generally adopts the intake method of iodine and carrier gas thereof.Subsonic speed section note iodine can obtain the mixing of good injection iodine and main oxygen stream, and realizes dissociating of I2 in the O2 with helium high dilution (a1 Δ) air-flow.These gain medias expand subsequently in a supersonic nozzle, to reduce gas flow temperature, thereby have reduced the threshold value productive rate of realizing population upset and the desired O2 of postiive gain (a1 Δ).This method has successfully obtained application on many efficient COIL devices.But at subsonic speed note iodine, with respect to singlet oxygen generator (SOG) air-flow, the flow of iodine and carrier gas thereof be can not ignore, therefore the injection of iodine and carrier gas thereof can cause primary air pressure to raise and speed decline, simultaneously due to the subsonic speed section pressure of jet pipe is higher and also from the distance of optical cavity relatively away from, therefore the excited state particle quencher of subsonic speed section oxygen iodine hybrid plan loss is larger, and this will affect the operational efficiency of Chemical oxygen-iodine laser.
Inject in supersonic speed section by iodine and carrier gas thereof, can avoid pressure rising and the speed of the primary air of being given birth to by injected gas miscarriage to decline, to reduce the quenching process of O2 (a1 Δ), for downstream laser provides more O2 (a1 Δ).Another advantage of supersonic speed section note iodine is the COIL that this scheme is more suitable for doing in non-helium carrier gas, as nitrogen carrier gas COIL or carbon dioxide carrier gas COIL.The main advantage that these gases do carrier gas is that cost is lower, but because the molecular weight of these gases is all greater than helium, therefore its flow velocity in pipeline is also corresponding slower, in this case, if still adopt subsonic speed section note iodine, can cause larger O2 (a1 Δ) loss, therefore in this case, supersonic speed section note iodine is an inevitable choice.In addition supersonic speed is mixed the also likely more uniform power distribution of acquisition in chamber, laser performance is showed to the impact bringing thereby reduce Deformation of resonator mirror.
The research abroad supersonic speed oxygen iodine being mixed probably starts from the end of the nineties in last century.The Madden of USAF Weapons Laboratory in 1999, T.J. reported their the analog computation comparisons to the upper several different note iodine schemes of Investigation on Supersonic Coil device (helium is master dilution gas) with the people such as G.D.Hager, comprised that subsonic speed section is injected iodine molecule, supersonic speed section injects iodine molecule and supersonic speed section is injected iodine atom etc.They calculate by CFD model, have compared the performance of the laser of above-mentioned three kinds of schemes, and two supersonic speed section note iodine schemes have been obtained to more positive result.Israelis has designed the oxygen iodine mixing jet tube of the horizontal streamer iodine of a kind of supersonic speed section subsequently, and on COIL, has carried out a series of experimental exploring, has obtained good achievement in research.Japanese has also done a lot of exploration work in this respect, and they have designed a kind of supersonic nozzle of " X " shape innovatively, has greatly improved the efficiency that supersonic speed is mixed, and its chemical efficiency has reached 33% left and right.
Based on forefathers' some achievements in research and research experience, the design of this patent novelty the oxygen iodine mixing jet tube that mixes of a kind of supersonic speed concurrent flow, coordinate the enhancing of the disturbance fin of particular design to mix, this jet pipe is being successfully applied aspect COIL operation and flow-field test research.
