Numerical solution to the problem of gas exhausting from planar and axisymmetric vessels

A study is made of a gas jet exhausting from an infinite vessel with planar or axisymmetric walls whose generator makes angles ± with the symmetry axis of the jet. The flow regime is determined by the pressure ratio _a = P_a/P_O, where P_O is the pressure in the vessel and P_a the pressure in the surrounding space.Translated fron Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 2, pp. 174–176, March–April, 1982.We thank M.
