As water networks around the world age, leakage and water main breaks are becoming an increasing problem. Leakage rates of 10-30% are typical in North America, and most cities suffer from hundreds (or thousands) of water main breaks every year. Echologics has developed the EchoShore ... 詳細を見る
Prior work has analyzed the case of planar Poiseuille ferrofluid flows in planar ducts stressed by uniform sinusoidally applied fields transverse and perpendicular to the duct axis. The coupled linear and angular momentum conservation equations with imposed magnetic flux density, Bx and ... 詳細を見る
Neutral Beam Injectors for ITER require development of negative ion sources and beams with carefully reduced beam divergence. In the accelerator this is compensated by the focusing due to the fringe effect of the electric field, while in the drift region, where the beam is propagating ... 詳細を見る
Viscous fingering is a topic of interest since the beginning of computational fluid dynamics. Here we focus on the classical constellation of miscible displacement, as it has been investigated in Hele-Shaw cells. A temperature or salinity front is entering with a fluid that has a ... 詳細を見る
We present an optimization procedure to optimize the maximum coupling of free space optical wave to surface plasmon. Shape derivative from shape sensitivity analysis is calculated, and the corresponding partial derivatives of the objective functional with respect to finite number of ... 詳細を見る
This paper presents a study on the propagation modes of electromagnetic waves through a step index fiber optics. To analyze the propagation of electromagnetic field, a simulation in Comsol 4.0 has been implemented using two different optical fibers. Obtaining the propagation modes, ... 詳細を見る
Numerical study of aerodynamic characteristics in steady laminar supersonic flow over a double wedge airfoil is carried out using commercially available finite element based CFD tool COMSOL Multiphysics. The aerodynamic characteristics of double wedge airfoil like lift and drag are ... 詳細を見る
Electro-active polymer (EAP) based actuators are one of the suitable contenders for use in artificial muscles based bio-medical application because of their bio compatibility and lower active actuation voltage requirement phenomenon. At present Ionic polymer metal composites (IPMC), a ... 詳細を見る
Hazardous for the transmission lines is not only the static ice load, but also the aerodynamic instability of iced cables. It can lead to large amplitude oscillations at low frequencies. Also, twisting due to asymmetrical iced cables may increase the fatigue rate. In extreme events, ... 詳細を見る
COMSOL Multiphysics® is used to simulate the transport phenomena in arc welding of Nickel to 304SS. Electric Currents (ec) and Magnetic Fields (mf) are used to solve for the Lorentz force which is one of the volume forces. Laminar Flow (spf) is used to simulate flow field. The Lorentz ... 詳細を見る
