..., a novel model is proposed to predict the influence of interface shape on stratified flow. Dynamic contact angle theory and minimum energy method are introduced to solve the momentum equations with a curved interface and dispersed phase holdup in the lower water layer or the upper oil layer, respectively...

... advantage as well as a particular disadvantage. The primary difficulty is that models of suitable fidelity, in terms of both rate dependence and time dependence, are essential to optimization of both system design as well as system operation. stratified flow thermal energy storage convection...

... drop and size downstream processing facilities. The most important parameters are pipe geometry (pipe diameter and orientation), physical properties of the gas and liquid (density, viscosity and surface tension) and flow conditions (velocity, temperature and pressure). Stratified flow and annular flow...

.... For annular flow tests, thicker and harder deposits were observed at low superficial liquid velocity than at high superficial liquid velocity. In stratified flow tests, no wax deposition was observed along the upper portion of the pipe. Figure 5 shows the average wax thickness along the test section...

... oil was used. The line was connected to a freshwater network to control the input water volume fraction. A gate valve installed at the pipeline inlet controlled the oil flow rate. The transition from stratified flow to dispersed flow was determined by measuring the transversal water fraction profile...

... technology oil technology stratified flow Two-phase flow in the petroleum industry is a very common occurrence because of the simultaneous production of gas and liquid from hydrocarbon reservoirs. When gas and liquid flow simultaneously in a pipe, various flow configurations or patterns may form...
