The four foot diameter class A evaporation pan is used by the scientific community as the standard for determining evaporation rates for a number of purposes. The COMSOL Multiphysics® software provides the necessary tools to adequately develop synthetic estimates of evaporation values for input into hydrologic simulation models and other earth science applications. This paper presents ...

Rechargeable batteries solve electrification and communication problems. As examples, hybrid battery-diesel generator power supplies efficiently power cell towers in remote locations, detached from the power grid. Large battery banks are used to load level user power requirements, reducing stress on power generation infrastructure. Batteries firm the output capacity of intermittent wind ...

A bidimensional and pseudo homogenous model was proposed for the study of mass transfer in the bioadsorption process of chromium VI in the S-layer of immobilized Bacillus sphaericus in a packed column. The implementation of such a model in COMSOL Multiphysics will be explained in detail and the final results presented. These include chromium concentration profiles along the column and its ...

Targeted drug delivery systems have been wildly studied in cancer therapy due to the toxicity of most of chemotherapeutic drugs. Nanoparticles can be attached to the small molecules of the drugs and serve as drug carriers to deliver the drug molecules into the area of interest. In this research, polymeric microspheres containing biodegradable poly(D, L-lactide-co-glycolide) (PLGA), magnetic ...

Mathematical optimization can be used as a computational engine to generate the best solution for a given problem in a systematic and efficient way. In the context of monolithic converter systems, the parameter estimation problem (or inverse problem) is solved using Partial Differential Equations (PDE)-based models of the physical system coupled with an optimization algorithm. These problems are ...

When rice is subjected to intense heating, it results in rapid evaporation of liquid water to vapor. As a consequence, large pressures are generated within the kernel in a span of 15s resulting in large volume changes causing the kernel to puff rapidly. Under suitable conditions, the ratio of initial volume to volume after puffing could be as high as 10. Rice puffing process is a complex ...

The Atmosphere Revitalization Recovery and Environmental Monitoring (ARREM) project was initiated in September of 2011 as part of the Advanced Exploration Systems (AES) program. Under the ARREM project, testing of sub-scale and full-scale systems has been combined with multiphysics computer simulations for evaluation and optimization of subsystem approaches. In particular, this paper describes ...
Computational Modelling of Fluid Dynamics in Electropolishing of Radiofrequency Accelerating Cavities - new

Electropolishing is an electrochemical process that radiofrequency accelerating cavities undergo in order to improve their inner metal surface finishing. This is performed prior to their installation into particle accelerators, in order to enhance their accelerating properties. Using COMSOL Multiphysics® software it was possible to model the process throughout the cavity and study the fluid ...

Within wool textile industries, a very important role is played by the so-called finishing processes, in which the textile substrate undergoes steam treatments to achieve the desired level of stabilisation and appearance. Process parameters, namely temperature and moisture content, are known only at the beginning of the process but not in the textile material being treated, where the actual ...
