Low-density jets beyond a sonic nozzle at large pressure drops

Free underexpanded jets in a quiescent medium: A review

“…Thus, one may easily find experimental works [66,144,145,[30][31][32]157,70,134,135,[191][192][193][194][195][196][197][198][199][200][201][202][203][204][205][206][207]148,151,35,77,38,39,15,64,40,142,82,123,159,42,127,59,55,51,87,60,122,150], as well as theoretical ones [133,74,…”

Self-ignition and explosion of a 13-MPa pressurized unsteady hydrogen jet under atmospheric conditions

“…Thus, the result obtained in Ref. [27] can apparently be extended to light gases, at least, to hydrogen. Note that in Ref.…”

“…When authors of work [27] analyzed the outflow of N 2 , air, and CO 2 from the sonic nozzle, they found that at N > 100 and the Reynolds number at nozzle cut Re n ! 200, on the jet axis behind the Mach disk the flow velocity did not become higher than the sonic velocity.…”

“…According to [27], in the case of a steady hydrogen flow at N > 100 downstream of the Mach disk, the supersonic velocity cannot be maintained further in the central region of the flow, and the first "barrel" remains to be the only one. Closely behind it in the flow, the static pressure is set equal to the ambient atmospheric pressure.…”
