This work concerns the performance of an oxidation catalyst used in a NOx storage and reduction system. The oxidation of NO is the main objective of this study, where the presence of CO and propene has also been taken into account. Experimental data has been determined on a monolithic ... 詳細を見る
The design and construction of ultra-high vacuum (UHV) systems for the study of surface reactions has lead to high impact innovation in a myriad of industries. A small volume reactor compatible with ultrahigh vacuum (UHV) surface-science instrumentation has been designed, modeled and ... 詳細を見る
Cellular-level oxygen consumption and cell viability models incorporating physiologically realistic assumptions and fully scaled 2D/3D geometries have been implemented in COMSOL Multiphysics for isolated pancreatic islets. Oxygen consumption was assumed to follow Michaelis-Menten–type ... 詳細を見る
In this study, COMSOL Multiphysics is applied in order to simulate reacting flows for duct burner systems arranged in the post-firing section of a Heat Recovery Steam Generator of a combined cycle power plant. Two- and three-dimensional simulations are carried out in order to ... 詳細を見る
A novel mechanism for the carbothermal reduction of Ilmenite is proposed and validated with the help of a comprehensive mathematical model. A time-dependent isothermal pellet-grain model is used to simulate the kinetic behaviour of a spherical pellet of ilmenite (FeTiO3) in CO/CO2 ... 詳細を見る
The temperature maintenance plays a crucial role in the transportation of heat sensitive materials like fruits, vegetables, food products and blood etc. The refrigeration of these products (during transport) utilizing energy from fossil fuels burning will involve CO2 emission. Thermal ... 詳細を見る
Volatile Organic Compounds (VOC) are a wide range of carbon based organic chemical compounds which evaporate easily at room temperature referred as volatile in nature. Human exhaled breathe consists of carbon dioxide (CO2) along with more than 3000 Volatile Organic Compounds exists like ... 詳細を見る
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 ... 詳細を見る
随着人类日常活动对制冷需求的不断增加，传统散热系统不仅消耗大量的能量，而且产生过多的废热和CO2的排放。外太空作为温度只有3K的冷源，热量通过大气透明窗口可以产生显著的辐射散热，特别是在白天仍然可以实现零能耗的降温。白天辐射制冷功率Pcool (Tr )可以写成： Pcool (Tr )=Prad (Tr )-Patm (Tatm )-Psun-Pnonrad Prad (Tr )是材料辐射的能量，Patm (Tatm )是材料吸收大气辐射的能量，Psun是材料吸收太阳光的能量，Pnonrad是材料与环境通过传导对流交换的能量。 为实现高效的制冷功率 ... 詳細を見る
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 ... 詳細を見る
