High pressure counterflow CHF.
… of the experimental results of a program in countercurrent flow critical heat flux. These experiments were performed with Freon 113 at 200 psia in order to model a high pressure water system. An internally heated annulus was used to model a fuel pin in a channel. Only low flowrates were …

STUDY OF THREE-PHASE AIR-BRINE-SALT COUNTERFLOW IN AN INCLINED PIPE
Gas-liquid-solid counterflow (GLSCF) in inclined pipes occurs in various industrial processes, including oil and gas production and desalination systems. This thesis presents an experimental investigation of GLSCF in a 2-inch pipe inclined at 30°, utilizing air, saturated brine, and salt particles. …

Micro-Scale Simulation of Evaporation, Condensation and Transport in Porous Media
Sub-pore scale modeling of flow in porous media is gaining momentum. The concept of Digital Core Analysis deals with measurements of virtual core and the purpose of such modeling is to replace conventional and special core analysis when the latter are not feasible. One of the challenging concepts …

Overall mass-transfer coefficients for a homologous series of poly glycol ethers between toluene and water
… concentration of approximately 64 per cent. A countercurrent-flow, 1-1/2-inch diameter, horizontal, pyrex glass tube, eight feet long with an interfacial surface area of one square foot, was used for the extraction tests. The feed concentration ranged from 9.10 to 15.18 weight per cent of …

A Unified Model for Multi-Phase Flow and Heat Transfer in Wellbores
<p>Multiphase flow is a common occurrence in the chemical and petroleum industries. The objective of this study was to apply the principles of multiphase flow to the production of petroleum fluids. A unified model was developed to predict the pressure profiles in wellbores using models available in …

Mathematische Modellierung des MDEA-Absorptionsprozesses
… absorption has one main advantage: i.e. a countercurrent flow of both gas stream and scrubbing liquid can be obtained easily. Thus the gas loaded liquid leaving the absorption column can directly be recycled in a desorber and used for absorption again in a continuous process. For this …
