An experimental study of the properties of plane jets issuing at various angles into a cross-flow of air was conducted to obtain information relating to the momentum diffusion properties of the jet flow in order to provide a background for predicting the feasibility of the preswirl concept of the Volumetric...
Experimental data are reported for the time-averaged
local radiative and total heat transfer coefficients for
both an array of horizontal tubes as well as a single
horizontal tube immersed in a large-particle fluidized bed
at elevated temperatures. Spatial-averaged heat transfer
coefficients computed from the local values, using a simple
trapezoidal...
In this thesis the critical parameters involved in the
dislodgement and deformation of microbubbles in laminar
channel flow, are determined and evaluated. Experimentally
the effects of surface tension, viscosity, fluid flow rate,
density, and bubble diameter on bubble dislodgement were
evaluated. A theoretical scale analysis was performed which
provided a...
Bidirectional reflectance is a fundamental property
used for the analysis of radiative heat transfer. It is a
form of reflectivity in which the spectral and directional
dependencies of both the beam incident on a surface and the
beam reflected from the surface are specified.
A new system has been designed...
During the operation of phase-change ink-jet printers a bubble formation
phenomenon often occurs. These bubbles are detrimental to the operation of
the printer and substantial efforts are made to remove them. The objective of
this research was 1: to develop a fundamental understanding of how bubble or
void formation occurs...
