The fabrication using silicon micromachining and characterization of an acoustic Lamb wave actuator is presented. The intended use of the device is for mass transport and sensor applications. The device consists of dual interdigitated transducers patterned ...
The fabrication and characterization of a microfabricated acoustic Lamb-wave device driven by a piezoelectric PZT (modified lead zirconate titanate Pb(Zr-x,Ti1-x)O-3) sol-gel thin film for use in mass-transport, mass-filtering and fluid-delivery systems ar ...
Micro-macrosegregation calculations have been performed for a rectangular cavity containing either a Pb-48 wt pct Sn alloy or a Sn-5 wt pct Pb alloy. The numerical results calculated with a finite volume method (FVM) and a finite element method (FEM) are c ...
Liq. film mass transfer coeffs. in packed beds and strings of spheres were calcd. theor. using a penetration model for the mass transfer combined with the hydrodynamics of a laminar spherical falling film. The predictions were tested with packed beds varyi ...
Lack of precision and inconsistencies in existing correlations, an attempt was successfully made to develop a new and more mechanistically based correlation (Kattan, 1996 [1]) for boiling inside plain tubes. This new general correlation is original in that ...
The influence of capillarity on the near-plane front solidification of metal matrix composites is examined by analysis of the one-sided solidification of a binary alloy in a planar interstice of constant width in the limit of low Peclet number. We assume t ...
The substitution of old refrigerants in refrigeration systems, heat pumps and organic Rankine cycles for heat recovery, request a good knowledge of heat transfer properties of substitute fluids. The test measurmements in LENI test facility (concentric tube ...
The effective area for mass transfer of the Sulzer structured packing Mellapak 125.Y, 250.Y, and 500.Y was measured under industrial-scale operating conditions, with a broad range of gas and liq. flows, in a pilot plant with a column having an internal dia ...
The two-region model was developed originally to describe nonsorbing chemical transport in soils with dead-end pores based on the concept of mobile and immobile regions in the soil. It has been shown that the model can simulate solute transport in soils wi ...
In order to delay the occurrence of the 2D-3D growth mode transition in highly strained InxGa1-xAs epitaxial layers grown on GaAs (001) by molecular beam epitaxy, the mass transport at the surface should be reduced. This can be achieved by increasing the g ...
