... have been performed to design a lifting pump, which consists of two stages of impellers in series. Eulerian multi-phase model was applied using a CFD model. From the analyses, it was observed that backward flow occurred at the second stage of the lifting pump. No serious accumulation or plugging...

..., the two-phase flow consists of a continuous liquid phase and a dispersed solid phase. If the flow is laminar, the motion of each solid will follow a smooth trajectory and deterministic. However, the flow in a lifting pump will has random and turbulent path. For the modeling of a lifting pump, three...

... in production method & modeling area will be presented. INTRODUCTION It can be said that natural gas utilization of Japan started from the construction beginning the pipeline between Niigata and Tokyo of 1961 and the procurement of liquefied natural gas from Alaska in 1969. Afterwards, the introduction...

... ABSTRACT: The decomposition of methane hydrate in aqueous solute is modeled and analyzed numerically. To simplify this problem, a single spherical pellet of the hydrate is considered and flows over the pellet are solved by a 3-D CFD method by using unstructured grid system. The decomposition...

... to incorporate into the model not only technical technology parameters (usually expressed in measurable quantities) but also adequate system of economic evaluation (postulations, assumptions, prerequisites, conditions, criteria) and decisive market aspects including distribution chain for products...
