A note on the stability of steady inviscid helical gas flows

  • Knut S. Eckhoff (a1) and Leiv Storesletten (a2)
Abstract

A necessary condition for linear stability of steady inviscid helical gas flows is found by the generalized progressing-wave expansion method. The criterion obtained is compared with the known Richardson number criteria giving sufficient conditions for stability.
