Reactive transport models (RTM) that couple physical and chemical processes are commonly used to solve a large variety of problems in the environmental industry. There are a series of codes designed to solve this kind of problems. However, their use requires typically much effort due to ... Read More
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 ... Read More
管道输送是油气能源长距离输送的重要途径。目前管道连接多采用焊接完成，焊接是一个复杂的非平衡物理化学过程，焊接接头各组成部分的成分、组织和性能都存在差异，同时还容易产生裂纹、气孔、夹杂和未熔合等焊接缺陷和较大的残余应力，使得焊接接头成为管道工程中的薄弱环节。在服役介质中，焊接接头存在宏观腐蚀电池与微观腐蚀电池耦合的多相电化学反应而引起局部腐蚀，可能导致整个构件失效，引发严重的安全事故，造成重大的经济损失甚至人身伤亡。利用 COMSOL Multiphysics® 多物理场仿真软件的腐蚀模块和二次电流分布接口对 X80 钢焊接接头在 CO2 饱和的 NACE ... Read More
COMSOL Multiphysics software, when properly configured, can readily solve modeling problems in the laminar flow regime using the standard Navier-Stokes equations or in the fully turbulent flow regime using the kappa-epsilon model. Failure to solve a particular model is typically ... Read More
Electric Arc Furnaces (EAF) use graphite electrodes to strike an arc to melt scrap steel, recycling it for further use. These graphite electrodes oxidize and are consumed over time. To maintain operation new electrodes are attached to others via a joint of complex geometry and fed ... Read More
In industrial countries, people spend most of their time indoors. Stringent heat-insulation measures in combination with deficient ventilation have a negative impact on indoor air quality [1]. Integration or retrofitting of a photocatalytic oxidation or PCO reactor into continuous flow ... Read More
Introduction: Ongoing work to improve water and carbon dioxide separation systems to be used on crewed space vehicles combines sub-scale systems testing and multi-physics simulations. Thus, as part of NASA’s Advanced Exploration Systems (AES) program and the Life Support Systems ... Read More
Electrochemical Machining with a closed electrolytic free jet is a special procedure to generate complex micro structures by help of anodic dissolution. The work piece shape is fabricated by supplying an electrolytic current through an electrolyte jet ejected from a small nozzle. In ... Read More
Worldwide, the leading cause of mortality in children is acute respiratory infection, primarily associated with pneumonia. One of the essential tools used to treat life-threatening hypoxemia due to pneumonia is the appropriate use of supplemental oxygen. While oxygen therapy is ... Read More
Studies of poroelastic systems increasingly utilize numerical modeling. Especially for geotechnical applications models are set up as a tool to understand phenomena in porous media that deform due to changes of the hydraulic regime, or in which the flow field is affected by changes of ... Read More
