Prediction of Pressure Drop in Vertical Air/Water Flow in the Presence/Absence of Sodium Dodecyl Sulfate as a Surfactant

Abstract Details

2013, Master of Science (M.S.), University of Dayton, Chemical Engineering.
The aim of this thesis is to develop a better approach for predicting pressure gradient in vertical multiphase flow with and without use of Sodium dodecyl sulfate (SDS) as a surfactant and to develop a program for the prediction of pressure drop by using Microsoft Visual Basic in Excel. Data was collected from four fixed liquid superficial velocity at different ranges of gas superficial velocity in a 0.052m i.d. and 10m long, clear PVC pipe. Results indicate that the addition of SDS resulted in reducing surface tension between phases from 72 to 64 mN/m, decreasing pressure drop by approximately 26% and also Hasan and Kabir model for Air/DI water and Hagedorn and Brown model in the presence of SDS in the mixture is the best model and leads to a reasonably accurate pressure gradient according to measured pressure drop.
