Previous to the present work, a formal calculation was approved [1,2] to support the operation of the High Flux Isotope Reactor (HFIR) Horizontal Beam-Tube 1 of 4 (HB-1). The present calculation [3,4] repeats the previous work using COMSOL Multiphysics® software and extends the analysis ... 詳細を見る
Acute respiratory distress syndrome (ARDS) is a severe lung disease caused by a variety of direct and indirect insults. The main treatment for ARDS is mechanical ventilation. The ventilation of fluid filled lungs involves the propagation of microbubbles over a layer of epithelial cells. ... 詳細を見る
With offshore oil and gas exploration and production moving into ever deeper waters, the suspended length of marine risers (transporting hydrocarbons from the seabed to the surface) can easily exceed 3000 meters. One of the major design requirements for risers in (ultra) deep water is to ... 詳細を見る
During semiconductor manufacturing, finished silicon microchips need to be released from a carrier tape they stick to by an adhesive. This is done by vacuum forces that (a) hold the chip flat from above and (b) pull the tape off from the chip underside. Sounds simple, but is very tricky ... 詳細を見る
The electromagnetic pumping (EMP) of electrically-conducting fluid is of growing interest for many industrial applications requiring precise flow control, enabling stopping or reversing flow direction without any moving parts or mechanical devices. Presented in this work are the results ... 詳細を見る
An external magnetic field imposed on a ferrofluid with a temperature gradient, results in a non-uniform magnetic body force, which leads to a form of heat transfer called thermomagnetic convection. A magnet placed near the device will always attract the colder ferrofluid more than ... 詳細を見る
Vortex-induced vibration is a major cause of fatigue failure in submarine oil and gas pipelines and steel catenary risers. Even moderate currents can induce vortex shedding. In this paper, COMSOL Multiphysics is applied to study the flow pattern around submarine pipeline spans, and ... 詳細を見る
Venovenous extracorporeal life support (VV-ECLS) provides gas exchange support for severe lung failure by using an extracorporeal circuit consisting of a blood pump and an artificial membrane lung. Blood is withdrawn from a cannula placed into the inferior vena cava, and returned from ... 詳細を見る
Simulation of the flow behaviour of non-Newtonian fluids with high viscosities leads to special material models with specific material parameters. In this presentation, a material model consisting of 4 material parameters describing the flow itself and also the wall slip is presented. ... 詳細を見る
This paper presents model development and simulation results for a microdroplet generator capable of internally measuring the volume of dispensed droplets. The system’s integrated sensing is enabled by storing compressible gas adjacent to the dispenser’s liquid reservoir. During ... 詳細を見る
