Abstract: Numerical simulations are conducted for the wave initiation, growth, and saturation at the oil–water interface in core-annular flow (CAF). The focus is on conditions with a turbulent water annulus, but the laminar water ...

Abstract: Stratified gas–liquid flow is a flow regime typically encountered in multiphase pipelines. The understanding and modeling of this regime is of engineering importance especially for the oil and gas industry. In this work, ...
