Pyrochemical process based on molten salt electrorefining is ideally suited for reprocessing spent metallic fuels from Fast Breeder Reactors. In this work, a heat transfer analysis of the Electrorefiner cell was conducted to develop a basic tool for designing of the engineering–scale Electrorefiner. The focus of this work is to find out steady state temperature profiles of cover gas and molten ...

Bread baking is a complex process where various physiochemical and biological transformations take place simultaneously. A two dimensional model was developed for the bread baking process taking into account of volume expansion, heat and mass transfer processes. Phase change and evaporation-condensation mechanism were incorporated by defining thermo-physical properties of bread as a function of ...

We report the results of simulation showing light coupling in waveguides through prism coupling method. Prism coupling method of light coupling in waveguides is a dominant method adopted by photonic device fabricators. It is necessary to understand the effect various parameters on light coupling in such processes. We used industry standard PDE solver COMSOL Multiphysics to study and analyze the ...

A large amount of research work has been carried out in many countries to determine the viability of radioactive waste disposal in deep geological repositories. It is well known that excavation can cause damage around underground openings. On the other hand, the mechanical damage can influence the stability of the opening and the flow characteristics of the rock mass. In addition, all physical ...

Multiphysics optimization of thermal-fluid systems is an emerging area of interest with application to the development of high performance cooling technologies for electronic systems. This paper builds on previous work focused on the development of a computational platform for numerical optimization. Specifically, a sample optimized topology is briefly described, and the final result is ...

COMSOL Multiphysics® 4.0 was used to study conductive and convective heat transfer from the human eyeball to the surrounding air. Postmortem temperature decay curves were collected in eyeballs of numerous human corpses. Of course, these curves represent only a portion of the complete temperature decay curve, since the pathologist is able to start collecting temperature data only after some ...

Nowadays, to go along with sustainable development and for cost matters, automotive heat exchangers are built with less and less aluminum and the process costs are being cut. However, the real mechanical response is a plastic shakedown, which is why we need to model the cyclic response as well as to find a fatigue criterion. A finite element model was developed using COMSOL Multiphysics to ...

COMSOL Multiphysics was used to simulate an experiment in which the hygroscopic swelling in an epoxy material was measured along a temperature ramp. A simultaneous solution was sought for temperature and moisture concentration distribution in a moisture loaded epoxy sample. Initially the multiphysics problem was broken down into two separate cases - transient heat transfer analysis and ...

NASA and the Department of Defense have interest in the development of satellites which are several orders of magnitude smaller than those currently in use. These ‘nanosats’ will require new propulsion systems to offer precise thrust and impulse-bit characteristics on the order of 10-100 μN and 100-1000 μNs respectively. To meet these demands, a pressure-driven MEMS-based ...

In this paper, we develop a mathematical model to simulate the movement of bacteria into and within a capillary segment. Also, we model the transportation through capillary walls by means of anisotropic diffusivity that depends on the pressure difference across the capillary walls. By solving the model using COMSOL, it was possible to predict the concentration of bacteria at points within the ...
