Abstract
Annular gas-liquid flow was investigated using high-speed modification of LIF technique. The evolution of liquid film surface was studied with high spatial and temporal resolution. It was found that all waves may be classified into primary and secondary waves; all the secondary waves arise due to instability of the back fronts of primary waves. The areas of inception and velocity of secondary waves were compared for annular flow with and without entrainment. The similarities and differences of wavy structure in both cases were demonstrated.
