The split of horizontal stratified flow at a large diameter T-junction

Phase split data have been obtained for a horizontal stratified flow approa ching an equal diameter (0.127 m diameter) junction. In addition, the shape and position of the interface of the flow approaching the junction have be en measured. The information has been combined to effect improvements to mo dels to predict the phase split. The improved model gives good predictions for larger and smaller diameter T-junctions. Further improvements, particul arly to remove empiricism, are required.
