Study On Liquid-Liquid Two-Phase Laminar Flows In Horizontal Pipes

After analyzing overall domestic and foreign literatures on liquid- liquid two-phase laminar flow in the horizontal pipes, those are studied mostly in hydraulic parameters. Especially it is short of studying by hydrodynamics microcosmically on sorts of clear interfacial liquid-liquid two-phase laminar flow in the horizontal pipes. It is not adaptive to applications in liquid- liquid two-phase laminar flow in engineering.Starting from N-S equations of fluid mechanics, the flow mathematical models of clear interfacial fluid-fluid two-phase laminar flow in the horizontal pipes is established. Afterwards, a system of mathematical equations to completely describe the laminar flow in horizontal pipes is obtained. By means of the numerical solutions to deal with the systematical equations, utilizing computer-simulated techniques, the important flow laws to actual engineering are obtained. Applying the laws, the high-effectively transporting of viscous fluid can easily realizedIt is provided and consulted conveniently in the oik chemistry, circumstance , mill-run and convective thermodynamics to successfully calculate, especially on Bingham fluid, Non-Newton fluid.By means of changing non-square area into square area and changing a system of flow equations including unknown variables into a system of equations including hidden variables, it can be applied in the other areas of fluid mechanics.
