Numerical and experimental studies on the mixing characteristics of two jets with inclined angles in a rectangular chamber

다국어 초록 (Multilingual Abstract)

Mixing characteristics in a rectangular chamber are investigated using experimental and numerical methods. A mixing chamber withan axial inlet (representing fuel inlet) and a side inlet (representing air inlet) is designed. Two jets with different momentum ratiosthrough the two inlets are mixed in the chamber. Computational fluid dynamic simulation is validated by experimental data of particleimage velocimetry that measures flow velocity distribution. The momentum ratios of the two jets and the height of the axial inlet significantlyinfluence the penetration depth of axial jet into the mixing chamber and the pressure drops at recirculation zones.
