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 general relationship between the parameters.
Experimental results provided reasonable comparisons with
values calculated from the scale analysis. Non-dimensional
plots were generated of Weber number, at bubble
dislodgement, versus Reynolds number and Weber number as a
function of a non-dimensional bubble diameter. A calculated
velocity detachment equation was also produced. This work
is applicable to many areas of science and industry,
particularly in the field of ink-jet printing. / Graduation date: 1992
