Recent developments (1) in thermal metamaterials that enhance the response of thermoelectric generators (TEG) have revived the interest in TEG research. The COMSOL Multiphysics® software offers the unique opportunity to model TEGs with various cooling systems (air, water, etc) and ... 詳細を見る

Within the field of microfluidics, scientists and engineers have found ways to manipulate flow at the micron scale in order to downsize standard experimental procedures. These techniques boast faster results while consuming less resources. Microfluidic devices can be used for point-of ... 詳細を見る

Arc plasma can heat and melt the metal material and flows of molten metal can be affected by several forces such as Lorentz force which is ruled by current, Marangoni force controlled by surface tension, buoyancy force, and arc drag force. Usually, surface tension variation is determined ... 詳細を見る

Microheaters used for gas sensing applications have been studied analytically and experimentally. Previously reported microheaters at COMSOL® conferences have shed light on microheaters’ thermal properties, optimized geometries and power consumption—all based on steady-state analysis. In ... 詳細を見る

There is great interest in developing all-solid-state lithium-ion batteries. They are ideal micro-power sources for many applications in portable electronic devices, electric vehicles and biomedical engineering. The batteries are possessed of high energy and power densities, good ... 詳細を見る

Type I diabetes results from the autoimmune destruction of pancreatic islets and is a growing and cost intensive chronic health problem throughout the world. Monitoring blood sugar levels and recurrent intervention with exogenous insulin allows many patients to lead relatively normal ... 詳細を見る

One of the obstacles preventing photovoltaic and concentrated solar power technologies from scaling up to meet increasing electricity demands is the inevitable dust accumulation on the optical surfaces of solar collectors. The ideal location for solar power is arid environments due to ... 詳細を見る

The COMSOL Multiphysics® software has proved itself an invaluable tool for teaching "Transport Phenomena" to graduate and undergraduate engineers. In particular, the software allows us to visualize and explore solutions well beyond what students could do with pencil and paper. For ... 詳細を見る

A good approximation of rough surfaces and their random behaviour is very important in some engineering problems. Fractal modelling provide an alternative to generate rough surfaces based in statistically self-similar non-Euclidean geometries, as seen in [Fig. 1]. Through a frequency ... 詳細を見る

Acoustic metamaterials commonly use Helmholtz resonators to attenuate an acoustic signal at the resonator’s resonance frequency. The resonance frequency is only dependent on the geometry, which is shown by representing the Helmholtz resonator as a mass spring system using the lumped ... 詳細を見る
