The purpose of this research was to study the effect of capillary
tube dimensions on the apparent viscosity of an unstable dispersion
of two immiscible liquids. The study was limited to laminar
flow at a constant temperature.
The dispersions were composed of a commercial solvent,
Shellsolv 360, manufactured by the...
Merk's series solution to the momentum equation for steady
two-dimensional or axisymmetrical constant-property laminar
boundary layer flow was examined. Solutions were obtained to the
differential equations associated with the second term in the series.
Calculations using this series were made, and it was found to be unsatisfactory
because the second...
Sisson's formally exact series solution for momentum, heat and
mass transfer in steady two-dimensional or axi-symmetrical constant-property,
laminar boundary layer flow was examined. A new series
was proposed for the boundary condition accounting for the mass
transfer at the surface of the body on which the boundary layer is
formed....
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...
Described in this thesis is an investigation of the fully developed natural convection
heat transfer in a vertical channel formed by two infinitely wide parallel plates
maintained at a uniform wall temperature. Closed-form solutions for the velocity
and temperature profiles are developed along with local and averaged Nusselt
numbers. The...
The effects of varying flow rate ratio and Reynolds number on the momentum diffusion and flow development of two co-flowing, laminar streams in a rectangular microchannel are presented. The microchannel has an aspect ratio of approximately 16 with a width of 1006 μm and a height of 63 μm. A...
A two-dimensional model was developed to predict concentration profiles from passive, laminar mixing of concentration layers formed in a fractal-like merging channel network. Both flat and parabolic velocity profiles were used in the model. A physical experiment was used to confirm the results of the model. Concentration profiles were acquired...
