“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 ...

In 2016 the group of experimentalists from the Institute of High Current Electronics (Tomsk, Russian Federation) have been discovered a novel phenomenon related to atmospheric plasma jets that was called an “apokamp” (originated from Greek words “off the bend”). This new plasma jet ... Read More
Nowadays, gas and nuclear waste storage, shale gas and EOR exploitation rise the need to understand and predict the fate of multiphase flows in the underground. Various formulations for multiphase flow arise from different linear combinations of governing equations and choice of ... Read More
Within the ENHANCE European project, hybrid energy harvesters have to be designed and developed to supply small and autonomous sensors in automobiles. The focus of this work is particularly related to the harvesting of energy from the vibration of the vehicle and from the high ... Read More
COMSOL® models have been developed for teaching gas absorption fundamentals. Model results are compared to environmentally significant experimental results for removing CO2 and SO2 from air using water as solvent. For concentrated gas mixtures, the models are shown to be equivalent to ... Read More
A general purpose stainless steel micro reactor setup for methane conversion is being designed for research purposes. We intend to design and build a modular device that would be able to manage different types of reactions depending on the installed modules. The device should be able to ... Read More
The anode baking process has gained significant attention since the 1980s due to its importance in Aluminium industry. A good anode baking process strives to achieve multiple goals including reduction of NOx from emissions. NOx generation is mainly due to the high-temperature ... Read More
Emily Nelson received her PhD in Mechanical Engineering from the University of California at Berkeley. She is a senior research engineer at NASA Glenn Research Center and specializes in the formulation and solution of problems in microgravity science, multiphase flow, porous media, risk ... Read More
Various types of equation system formulations for modeling two-phase flow in porous media using the finite element method have been investigated. These allow for equation manipulation such that the main differences between the formulations are the dependent variables that are solved ... Read More
An optimal control problem (OCP) is studied to a PDE of elliptic type as well as state constraints. The resulting optimality system contains two PDEs, one algebraic equation and the so called complementary slackness conditions, i.e. dual products between function spaces. At this point, ... Read More
