Thin-source concentration dependent diffusion
… using a thin45 source of Ca tracer, rectangular geometry, and serial sectioning. The l6 2 pre-diffusion surface concentration was approximately 3xlO(Ca)-atoms!cm, which, for an average penetration depth of IOOum-300um, produces a maximum (post-diffusion) impurity concentration …

A Fourier Solution for Electromagnetic Scattering by a Covered Rectangular Cavity
… the plane-wave scattering from a two-dimensional rectangular cavity embedded in an infinite metallic surface that has been covered with a dielectric material. The transverse magnetic and transverse electric polarizations are both considered. The rectangular geometry of the embedded cavity allows …

Design of effective traveling wave sloshing absorbers for structural control
… design optimisation of the conventionally used rectangular geometry based on energy dissipation performance. Appropriate selection of water depth and container width is found to optimise energy dissipation within this shape. Further improvement in control performance is achieved by modifying the …

Preparation of anisotropic microparticles and their behaviour at liquid interfaces
… controlled shape and size with disc, oval and rectangular geometry have been fabricated. Monolayers composed of such particles at both the air- water and oil- water interfaces exhibit important differences between each other and spherical particles. The geometry of the monolayers at the …

Hydrodynamics, stability and scale-up of slot-rectangular spouted beds
Slot-rectangular spouted beds, with rectangular cross-section and slotted gas inlets, have been proposed as a solution to overcoming scale-up difficulties with conventional axisymmetric spouted beds. They can be utilized in gas/particle processes such as drying of coarse particles and coating of …

MULTISCALE MODELING OF III-NITRIDE CORE-SHELL SOLAR CELLS
… is divided into four coupled phases: 1) Geometry construction for the wurtzite lattice having hexagonal crystal symmetry and non-conventional crystal orientations; 2) Structural relaxation and calculation of atomistic strain distributions using the VFF Keating molecular-mechanics model, …

Wobbly winds in an ice age : the mutual interaction between the great continental ice sheets and atmospheric stationary waves
… approach shows that, in an idealized rectangular geometry, the height, shape, and orientation of the ice sheet are all dependent on the stationary wave that it creates. The fundamental competing balance is between the enhanced precipitation on the windward slopes, and the cold …

Large Eddy Simulations of Sand Transport and Deposition in the Internal Cooling Passages of Gas Turbine Blades
… cooling passages of turbine blades. A simplified rectangular geometry is simulated to mimic the flow field, heat transfer and particle transport in a two pass internal cooling geometry. Two major challenges are identified while trying to simulate particle deposition. First, no reliable …

Modelling of the liquid slag behaviour in the continuous casting mould
… in the complex transition from the SEN geometry – essentially a cylinder with two outlets set at a specific angle of 20o to the vertical, to the thin rectangular geometry of the mould which is designed to cast flat products. - The turbulence model, which was initially found to suppress …
