This paper presents a Buckley-Leverett analytical solution for non-Darcy displacement of two immiscible fluids in porous media. The multiphase non-Darcy displacement is described using a Forchheimer equation or other non-Darcy flow correlations under multiphase flow conditions. The analytical solution is used to obtain some insight into the physics of displacement involving non-Darcy flow effec...

A multiphase nanostructured ZrCu-base bulk alloy which showed a unique microstructure consisting of sub-micrometer scale Zr₂Cu solid solution, nano-sized twinned plate-like ZrCu martensite (ZrCu (M)), and retained ZrCu (B2) austenite was fabricated by copper mold casting. The observation of periodic morphology evolution on the fracture surface of the multiphase nanostructured ZrCu-base alloys h...

The interest in multiphase machines for high performance applications has been growing in recent years due to their potential advantages over three-phase machines. One of the possibilities of taking advantage of the additional degrees of freedom that exist in multiphase machines is the series connection of several multiphase machines, with the supply coming from a single multiphase inverter. Th...

Abstract This paper examined the cyclic deformation behaviour of multiphase low-carbon steel that was subjected to austempering heat treatments at four temperatures (190 °C, 230 275 and 315 °C) below martensite start temperature ( M s = 353 °C). The tests were conducted room temperature, under fully reversed strain-controlled conditions, with strain amplitudes in range 0.5–1.0%. microstructure ...

To understand and clarify the formation mechanisms evolution of complex inclusions in Ti-Ca deoxidized offshore structural steel, industrial steel were systematically investigated. The number density total generally decreased from Ladle Furnace (LF), Vacuum Degassing (VD), Tundish to final product except for Ti Ca addition. major during refining process CaO-Al2O3-SiO2-(MgO)-TiOx CaO-Al2O3-SiO2....

The simultaneous flow of immiscible fluids in porous media occurs in a wide variety of applications. The equations governing these flows are inherently nonlinear, and the geometries and material properties characterizing many problems in petroleum and groundwater engineering can be quite irregular. As a result, numerical simulation often offers the only viable approach to the mathematical model...
