الوصف
Creating a new model to estimate void fraction for gas-non-Newtonian flow is another
objective done in the present work. The void fraction is considered one of the most important
flow parameters used to describe two-phase flows in tubes. Void fraction is an important process
variable for the volume and mass calculation required to transport gas-liquid mixture in
pipelines, storage in tanks, metering, and custody transfer. Furthermore, it is important to
determine other flow parameters such as two-phase density and viscosity or the average
velocities of gas and liquid mixture. In addition, it plays a significant role in estimating and
modelling two-phase pressure drop and flow pattern transitions. The created void fraction model
is used to determine constants of general form posted by Butterworth[2]. Both developed void
fraction models give a good estimation for the void fraction with about 5% percent errors
compared with our experimental results and other available literature experimental results.
