Abstract

The study concerns the separated two-phase gas-liquid flow in a horizontal or slightly inclined pipe. The cross section of the cylindrical pipe is elliptical. After deriving the partial differential equations, the analytical prediction of the transition between stratified/non-stratified flows is obtained by using a linear stability analysis. The stratified flow, in a pipe having one of its cross section’s axes disposed horizontally, is more stable when this axis is the great major.
