Delayed Coking is a refining process, which takes heavy petroleum residue as a feed. A 2D axisymmetric stationary model was created to simulate this pre-run condition with nitrogen gas, as an attempt to calibrate the model before simulating with an oil residue. The single-phase laminar ... En savoir plus
This assignment deals with the modeling of a pressure controlled current-limiting valve. For this purpose the CAE-Software COMSOL Multiphysics® is used. Current-limiting valves are used as a measure of safety in many hydraulic applications. They are deployed in cases of a high decrease ... En savoir plus
Large centrifugal compressors, which are commonly applied in the oil and gas and in the process industry, may fail due to vibrations of the impeller. These vibrations are induced by pressure pulsations in a compressor stage. These vibrations can be especially strong in so-called dense ... En savoir plus
CO2 capture and storage constitutes a promising solution to control and reduce these emissions. Wellbore integrity is a key challenge to ensure long term safety and for public acceptance. For this objective, a two-phase flow model in porous media based on Darcy’s law has been proposed to ... En savoir plus
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 ... En savoir plus
2015年由美国大发起页岩气革命成功地使美国从油气进口国转变为油气出口国。这使得页岩气成为能源领域关注的热点。页岩气与煤炭和石油相比更为清洁，且储量更为丰富。开发页岩气的两项关键技术是水平井钻井技术和压裂改造地层技术。 然而，由于页岩相比于其他岩石水化学活性更强，导致在水平井钻穿储层过程中井壁极容易垮塌失稳。油基泥浆的使用可以克服上述问题，但成本昂贵且受环保限制。水基泥浆的普及依赖于对页岩水化的深入理解。在页岩水化反应过程中，温度场、离子浓度场、渗流场、应力场均不同程度地作用在井壁周围岩石，而且相互耦合作用随时间不断变化 ... En savoir plus
Safe preservation of mammalian cells for long term is essential for medical and pharmaceutical industries. Cryopreservation by conventional slow freezing and by vitrification below freezing temperatures are the most effective biopreservation methods compared to in vitro culture at ... En savoir plus
COMSOL Multiphysics® software is used to model the field joint application process on carbon steel pipelines for deep sea crude oil transportation, taking into account not only heat transfer, cure kinetics, and crystallization, but also thermal, cure and crystallization shrinkage and the ...

The aim of this research is to contribute with the development of Carbon Capture and Storage techniques by studying carbon dioxide (CO2) adsorption mechanisms in shale reservoirs. Gas desorption is considered a major gas production mechanism and has a relevant role in shale gas ... En savoir plus
Methanol synthesis is a typical reaction in heterogeneous catalysis. In this work, we have studied a laboratory fixed-bed reactor packed with a Cu/Zn/Al2O3 catalyst in both adiabatic and isothermal tubular operational modes. A methanol synthesis kinetic model was implemented in COMSOL ... En savoir plus
