Notes:
In horizontal two-phase flow, transition from stratified to slug flow occurs due to the nonlinear instability of finite amplitude interfacial waves. The nonlinear equations describing interfacial waves in stratified two-phase flow are solved by a multiple scales perturbation method. Instability criteria and amplification factors are determined. The phase velocities that are calculated to lead to amplification of finite amplitude interfacial waves are well below those based on linear stability criteria. This is in agreement with existing experimental data on transition from stratified to slug flow in horizontal channels.
