In oil and gas industries, electrical heaters are often used to control the internal pipe temperature. One important criterion for such test, is to maintain a uniform temperature range during the test. The objective of this study was to evaluate the heat transfer of one design of the ... Mehr lesen
Most reactor designs are based on pseudo homogeneous models. This paper studies the COMSOL simulation of a packed bed reactor using a 2-D heterogeneous model. The case considered was a packed reactor with spherical catalyst for oxidation of o-xylene in air to phthalic anhydride. Large ... Mehr lesen

In this work the authors report on a CFD simulation of a pipe flow model. Fluid mechanics are here combined with heat transfer phenomena. To create a mathematical model of a pulsed hot wire system i.e., the thermo-fluidic impulse response of a pulsed hot wire, a simulation model is going ... Mehr lesen
Waterflooding and steam-flooding are used worldwide for EOR. Recently, CO2-flooding has attracted global attention as a means of EOR as well as for carbon capture and sequestration. These processes cause significant changes over time in the fluid composition of oil reservoirs. This paper ... Mehr lesen
Organic-rich shale resources remain an important source of hydrocarbons considering their substantial contribution to crude oil and natural gas production around the world. Moreover, as part of mitigating the greenhouse gas effects due to the emissions of carbon dioxide (CO2) gas, ... Mehr lesen
“页岩气革命”使美国成功摆脱了对他国能源的严重依赖,目前我国页岩气的勘探开发也已取得了突破性成果,但是随着页岩气的开发,仍存在三大问题困扰着科学工作者和现场工程师:(1)页岩气开发过程中的渗透率演化规律尚未摸清;(2)在产气过程中,页岩气在产量上往往呈现出不确定性;(3)缺乏针对页岩气进行历史拟合和产量预测的数学工具。针对以上三个主要问题,我们定义非常规储层固有渗透率的演化是裂隙和基质之间物质传输和应力传递的结果,并建立了离散体模型研究孔隙变形与流体流动之间的耦合作用;以此为基础,我们建立双基质双重孔隙介质模型(连续介质模型)研究页岩基质变形与流体流动之间的耦合关系 ...
