Liquid-gas ejector is an energy conversion device capable of flowing air fluid by utilizing water based on the pressure difference between two fluids without using moving parts. This study aims to determine effect changes in nozzle geometry two-phase flow performance liquid-gas ejector. The method used conducting experiment whose stages include: determining parameter, primary rate, and secondar...

A new system “MSB-AD-V-FC (BEL JAPAN Inc.)” has been developed, which has made it possible to simultaneous measurement of a water vapor adsorption and a proton conductivity to PEM under various experimental conditions (Temp; 353-473K, Humidity;0-95%RH, Press; atmospheric pressure-1.0MPa). The upper mix-conditioned run to PEM enables in a single original chamber considering of both principles of...

Understanding the dynamics of pore-scale multicomponent gas and oil mass transfer across water "lms during hydrocarbon gas injection in petroleum reservoirs is important in the design of tertiary oil recovery schemes at the "eld scale. The water "lms prevent oil and gas coming into direct contact and, for miscible gas injection, delay the onset of miscibility. We use a pore-scale model to descr...

investigating the role of drought stress conditions on physiological characteristics of plant may provide means to understand basic drought resistance. differences in leaf emergence rate, leaf relative water content (rwc), membrane stability index (msi), leaf mass area (lma), net photosynthesis (anet), stomatal conductance (gs), transpiration rate (e), intercellular co2 concentration (ci), ...

This work focuses on the development and improvement of numerical tools for the simulation of catalytic monolith reactors. These simulations cover detailed descriptions of reaction mechanisms, transport in gas-phase and washcoats, fluid flow in single channels, and the entire reactor. In DETCHEM, the concept of building a transient model of the monolith reactor by the calculation of steady-stat...

hydrates are crystalline compounds similar to ice, with guest molecules like methane and ethane trapped inside cavities or cages formed by the hydrogen bounded framework of water molecules. these solid compounds give rise to problems in the natural gas oil industry because they can plug pipelines and process equipments. low dosage hydrate inhibitors are a recently developed hydrate control tech...

A gas kick simulation model for deep-water horizontal well with diesel-based drilling fluid is presented in this paper. This model is mainly based on the mass, momentum, and energy conservation equations. The unique aspect of this model is the fluid-gas coupling and the change of mud properties after the gas influx from the formation. The simulation results show that the gas in an annulus disso...
