AN IMPROVED VERSION OF CALCULATING THE PRESSURE TRAVERSE IN MULTIPHASE FLOW VERTICAL PIPEKeywords: pressure losses , multiphase flow , flow pattern , density , viscosity. Abstract: The quandary of predicting pressure losses in multiphase flow systems is not recent to the industryand it still does not have a complete solution that can cater for all types of flow conditions. This hasbrought about many particular solutions for limited flow conditions. This is as a result of the intricacyof multiphase flow and also the difficulty in analyzing even flow conditions that are limited. The newmodel estimated the Pressure losses and compressibility factor at each point of conduit as the fluidflows through the pipe rather than assumed average constant pressure and compressibility factor. Thenew method proposed was used to obtain the pressure traverse in three (3) different flow conditionsand the results obtained are more accurate as compared with those obtained using the methodproposed by other investigators: Poettmann and Carpenter; Fancher and Brown; Hagedorn and Brown.
