COMSOL Multiphysics provides a powerful numerical platform where various models for microchemical process technology components can be readily created for both education and research. This modeling tool allows chemical engineering students to focus on understanding the effects of various microchemical system component design and operational parameters versus coding and debugging of the numerical ...

Developers of numerical models who address the title problem face several hurdles, such as: (1), the need to formulate boundary conditions applicable in an unbounded region; (2), The need to specify conditions suitable to ensure a unique solution in a doubly connected region; and (3), The need to allow the interior boundary to have a sharp edge, such as a cusp. The aim of the work reported ...

Single photon emission computed tomography (SPECT) is a nuclear medicine imaging technique that uses gamma rays. It has been especially useful for bone scans, cardiac perfusion imaging, tumor scans and brain imaging. The main advantage of SPECT imaging is that it can target particular tissue receptors allowing one to focus on the imaging of the diseased tissue. In most cases Monte Carlo ...

In order to predict, improve and meet a certain set of performance requirements related to the indoor climate of buildings and the associated energy demand, building energy simulation (BES) tools are indispensable. Due to the rapid development of FEM software and the Multiphysics approaches, it should possible to build and simulate full 3D models of buildings regarding the energy demand. The ...

With the ever changing energy requirements & demand for better communication links across the planet, subsea umbilical & cable requirements are becoming more stringent. Where longer service life at a lower cost is now expected from manufacturers. In addition to this, with the need to exploit more sustainable energy sources from offshore wind & wave, where extreme weather conditions are ...

A numerical model was developed to make spatial and temporal predictions of the water quality for Brewster Lake, located in southwestern Michigan. The model considers the hydrodynamics of the lake, hydrologic conditions, physical, chemical and biochemical processes that take place in the lake, and nutrient loadings from the surrounding watershed. Physical, chemical, and biochemical data ...

In this paper a poly-optimization of the design of the electromechanical actuator is presented. The shape of the actuator is defined by the decision variables. The number of decision variables under consideration is up to ten but in the next step while the multi-coils system will be analyzed the number of decision variables will increase up to hundred, so the genetic algorithm has been used. The ...

We demonstrate the use of Comsol Multiphysics with Matlab to model signal generation in wide-bandgap semiconductor radiation detectors. A quasi-hemispherical detector design is compared with a simple, planar detector. Results show that the quasi-hemispherical design can simply and effectively compensate for the poor hole transport of most compound semiconductor materials.

This paper presents a finite element method based modeling and design of control for distributed parameter systems. First, models of distributed parameter systems in the form of lumped-input/distributed-output systems and structure of control loop are introduced. Next, modeling of temperature fields of the casting die as distributed parameter systems in preheating process is performed in COMSOL ...

The transfer of sucrose and fructooligosaccharides to melon and water to solution was modeled based on generalized form of Fick’s second law for simultaneous diffusion and resolved by the finite element method using the software package COMSOL Multiphysics® software. The diffusion coefficients, the mass transfer coefficient and the Biot number were determined using the simplex optimization ...
