Measured and Predicted Pressure Drops in Two-Phase Air Water Flows.
Abstract
Two-phase, air-water flow is studied in a horizontal pipe. Water injection methods are compared to determine an efficient means of attaining fully developed homogeneous flow. Wall shear forces are measured directly through flexures attached to a 'floating' test section. The pressure drops are compared to those predicted by the Lockhart-Martinelli and Chenoweth-Martin correlation schemes. A computer program is presented for data reduction. For the flow rates investigated it is concluded that the Lockhart-Martinelli correlation gives better results than does the Chenoweth-Martin scheme providing one knows the existing flow pattern. A new method is suggested for predicting the transition between the annular and mist flow regimes. (Author)
