LIF visualization of 3-dimensional hypersonic mixing
Abstract
Engines for hypersonic transport have problems on fuel-air mixing. To study the flows in such engines, the LIF technique is used, where PLIF (planar laser-induced fluorescence) is convenient because it gives information without any interaction with the flow. To provide a long-time-scale steady-state flow, an arcjet-type electric thruster is used, simulating the main air stream, where a side jet simulating hydrogen fuel is visualized by the iodine-LIF technique. The interaction between these two jets is shown.
