Abstract:

The software has been written based on Taitel and Dukler Model (1976), only applicable for Newtonian fluids and steady two phase gas - liquid flows which occur in horizontal pipes or the inclination angle less than 100. The model starts with the equilibrium stratified flow and assumes it is the case in the pipe and therefore variables of the flow are determined, including hL. Then, an analysis is performed to identify if the flow is stable. If it is, the stratified flow occurs. Otherwise, a flow which is different from stratified should exist and another analysis to determine the flow regime is the next step. The author uses Visual Basic for Applications (VBA) to program and numerical methods to solve non linear and implicit equations which results in better results compared to conventional solutions gained by scanning graphs and tables.
