Webof an annular two-phase flow in a helically coiled tube. For some high quality flows in helical coils, Banerjee [11] reported that at low liquid flow rates, but high gas flow rates, the liquid phase travels along the inside of the tube wall (nearest the coil axis), rather than on the outside wall as might be expected due to centrifugal forces. WebAnnular flow is a flow regime of two-phase gas-liquid. It is characterized by the presence of liquid fluid flowing on an annulus shaped channel. Annular flow is important in drilling and production in deviated and horizontal wells [2]. Concentric annular flows of fluids in pipes have had a number of engineering applications.
