Penetration of Gaseous Jets In Supersonic Flows

Investigation of injectant molecular weight effect on the transverse jet characteristics in supersonic crossflow

“…To satisfy the requirements in engineering, researchers mainly focus on time-averaged penetration height, mass fraction distribution, total pressure loss in the following four aspects, namely jet-to-freestream momentum flux ratio [4,[14][15][16][17], injection angle [4,[18][19][20], configuration of injection orifice [4,21], molecular weight [21][22][23]. However, limited by experimental measurements and numerical simulations, the turbulent characteristics of sonic jet in supersonic crossflow are not the major contents in the early studies.…”

Effects of oblique and transverse injection on the characteristics of jet in supersonic crossflow

“…And the influence of jet-to-freestream momentum flux ratio [12][13][14][15][16], configuration of injection orifice [15,17], molecular weight [17][18][19] on the averaged parameters are widely investigated for several years.…”

“…The time-averaged results obtained by hybrid RANSand computational studies[12][13][14][15][16], it is observed that penetration height of transverse jet primarily depends on jet-to-freestream momentum flux ratio J , as shown in eq.…”

Quasi-1D Compressible Flow of Hydrocarbon Fuel

“…The jet penetration is primarily determined by the momentum flux 2 u  of fuel jet. 20,21 Assuming the cross jet is a quasi-1D process, we can write the variation of …”
