An intelligent data-driven flow regime recognition method for horizontal air-water two-phase flow [PDF]

Flow regime recognition is very important in the two-phase flow measurement. However, considering that two-phase flow is much more complicated than single-phase flow, flow regime cannot be accurately identified by mechanism model.
