對於流場中著火過程的實驗研究,我們利用位於國立成功大學的反射式震波風洞來模擬出超燃沖壓引擎在馬赫六飛行條件下其燃燒室入口的流場環境(條件為M = 2.0, T0=2000K, p0=12MPa, T=1200K, p= 1.5MPa )。對於燃料的噴注(氫氣),我們設計出一座上游(背向)式爆轟管,並能成功產生達421K的預熱氫氣的噴注。在實驗中,我們在一平板上的一個直徑為2mm的噴孔中將氫氣噴注至超音速流場中。再以高速攝影機和紋影結合的方法對流場進行觀察,亦應用增強式攝影機(ICCD)記錄OH自然螢光影像,以探討其可燃性。

Fundamental to the success of hypersonic air-breathing propulsion system are the efficient injection, mixing, and combustion process that occur inside the combustion chamber. This research is focused on the self-ignitability of a transverse fuel, hydrogen gas, injected into a simulated supersonic combustor environment.
Our experimental approach uses a reflected shock tunnel located in National Cheng Kung University, Taiwan, to provide the high total enthalpy flow associated with the scramjet combustor entry condition of M = 2.0, T0 = 2000 K, p0 = 12 MPa, T = 1200 K and p = 1.5 MPa. A upstream (also called backward) detonation-driven shock tube is also built and used successfully to supply hydrogen fuel at up to T0 = 505 K and p0 = 16.5 MPa for the experiment. In the first set of tests, the ignition of the transverse hydrogen injection from a 2mm wall orifice in a flat plate. In the investigations, a high speed camera is used indicates the location of the shock structures and an intensify CCD (ICCD) detector with hydroxyl (OH) radical wave length filter ( 307 nm) is used to map the regions of ignition in the near-field by the intensity of OH-chemiluminescence. Results show that the significant spontaneous ignition can be clearly observed in the recirculation region caused by the interaction between the traverse hydrogen fuel jet and also in the large scale eddies structure in downstream. Two heat flux sensors and PCB pressure transducer are flush-mounded on the model and also help to give a sign of combustion.
