Natural-convection heat transfer in supercritical fluids
(2004)
The main objective of this study is to calculate the heat-transfer coefficients for natural convection from a heated, vertical flat plate into a supercritical fluid. In the first part of this work, an equation for the ...
Transient, three-dimensional numerical model of laser cutting processes in ceramics with phase change consideration
(2004)
Physical problems involving moving heat sources can be encountered in many industrial applications during material processing, including cutting, drilling, welding,
heat treatment, and surface alloying, to name a few. ...
Determination of an empirical correlation for the mass transfer coefficients of pharmaceutical powders in a fluid bed layer
(2004)
The pharmaceutical industry has four basic operations to produce tablets: mixing, drying,
milling, and tablet pressing. Fluidized bed drying of the pharmaceutical powders is one of
the most efficient methods, which is ...
Heat and mass transfer effects in air-cooled vertical tube absorbers
(2007)
Most of the models to predict the heat and mass transfer in vertical absorption chillers underestimate the heat and mass transfer coefficients. Generally the models put too many constraints such as: laminar profile, constant ...
