Abstract:With air and water as the working fluids, an investigation on the characteristics ofthe interfacial waves in gas-liquid two-phase flow in horizontal rectangular channel wasconducted by using two-parallel conductance probes to measure the instantaneous liquidfilm thickness and signal statistical analysis methods. Firstly, the interfacial waves weredistinguished and defined according to the experimental observations and their statisticalcharacteristics. Secondly, the statistical characteristics of the interfacial waves in amplitude,time and frequency domains were examined and analyzed. Moreover, the variations of theinterfacial parameters, such as wave frequency and wave speed, were also investigated withvariations of gas and liquid volumetric fluxes.
Keywords:gas-liquid two-phase flow  interfacial waves  statistical analysis
