Computer simulations are used to study mass transfer from a stationary composite cylinder---made of an inner, initially loaded, core and outer-coating semipermeable shell---subjected crossflow. The transition steady unsteady laminar flow regime alters the released solute spatial distribution efficiency (Sherwood number), which is found depend explicitly on shell permeability. cylinder internal ...

The experimental study of the pressure distribution around an obstacle formed by four cylindrical tubes three different diameters immersed in a transversal flow and at inclination angles with respect to was carried out. Air atmospheric used maximum 0.038 Kg / sec. For each cylinder bore spacing, is strongly influenced angle inclination, but only marginally affected (within working range). Due t...

Stacks of superconducting tape can be used as composite bulk superconductors for both trapped field magnets and for magnetic levitation. Little previous work has been done on quantifying the levitation force behavior between stacks of tape and permanent magnets. This paper reports the axial levitation force properties of superconducting tape wound into pancake coils to act as a composite bulk c...

A micromechanics based thermal model was developed to predict the temperature and degree of cure (DOC) distribution inside a unidirectional fiber reinforced composite during the curing process. Using the concentric cylinder assemblage (CCA) model as a representation of the composite microstructure, the effective thermodynamic properties of the composite were computed based on the fiber and matr...

Metals are common construction materials for heat exchangers. However, metals may suffer from failure due to corrosion, especially in harsh environments. Innovative thermally conductive polymer composite tubes based on polypropylene or polyphenylene sulfide filled with graphite have been developed. Crystallization fouling metal surfaces has extensively studied. data very limited. In the current...
