Transport Phenomena in Chemical Engineering involves three key aspects: Momentum, Heat and Mass Transport. These areas are described by differential equations which are solved for a particular problem using independent or a set of combined equations (e.g., water flowing in a heated ... Read More
铁芯电抗器具有损耗小、噪音低、维护简单、电抗值线性度好、设计寿命长等优点,得到了越来越广泛的应用。但由于电抗器通风散热不良，导致运行中不同程度的局部过热，造成匝间短路、烧损，甚至引起火灾，严重影响电抗器的安全运行。该问题涉及电-磁-热-流体多物理场耦合，电抗器正常运行时电阻损耗和涡流损耗构成主要热源。本文采用COMSOL Multiphysics®多物理场仿真软件，通过AC/DC模块、传热模块、流体模块对铁芯电抗器的电路、磁场、损耗和温升空间分布进行研究。首先施加激励分别得到铁芯、线圈的磁场及损耗密度分布，然后将铁芯及线圈的损耗值添加为插值，作为流场 ... Read More
Fusion is a form of nuclear energy which has impressive advantages from the point of view of fuel reserves, environmental impact and safety. If successful, fusion energy would ensure a safe, resource conserving, environmentally friendly power supply for future generations. In a world ... Read More
A 2nd-generation irradiation target holder is being developed at the High Flux Isotope Reactor (HFIR) of Oak Ridge National Laboratory (ORNL). This 2nd-generation holder design is focused on improving the loading and unloading of the targets by the HFIR operators since a large number of ... Read More
Photo-bioreactors generate biomass by providing a controlled environment for the cultivation of algae due to photosynthesis. Algae cultivation can be controlled through the operating parameters and bioreactor environment to allow for high productivity and the use of systems with large ... Read More
Air pollution caused by particulate matter (PM) is one of the most severe issues in urban environments. Urban green infrastructure (UGI), in particular green walls, have been proven to be capable of capturing PM via deposition on leaves. This phenomenon was assessed by numerical ... Read More
Optimization of mixing in microfluidic devices is a popular application of computational fluid dynamics software packages, such as COMSOL Multiphysics, with an increasing number of studies being published on the topic. On one hand, the laminar nature of the flow and lack of turbulence in ... Read More
Steam generators (SGs) are used in CANDU® nuclear reactors as heat exchangers to convert water into steam using heat generated in the reactor core. Ferrous trefoil broach support structures prevent excessive vibration of thousands of SG tubes. A probe that uses pulsed eddy current (PEC) ... Read More
The conventional route to hydrogen production is by steam reforming of methane (MSR) in a multitubular packed bed. With the increasing use of biodiesel as a renewable fuel, interest has grown in steam reforming of the excess glycerol produced as a side product (GSR). We use COMSOL ... Read More
This work deals with the quantification of the CO2 transfer rate from a bubble to the surrounding liquid in a bubble column. A model is successfully developed using COMSOL Multiphysics. The validated model is used to study the enhancement influence of chemical reactions on the transfer ... Read More
