Development of a droplet size model for the separated gas–liquid flow in horizontal pipe and its application

A new model for droplet size prediction in horizontal pipes under stratified and annular flow is presented. The developed model takes into account the effects of the gas velocity, liquid velocity, pipe diameter, and developing length on the droplet size. Four experimental databases of droplet size in air-water horizontal flow under atmospheric pressure were used in the model development. The experimental flow conditions of the database covered a...
