Abstract
  • 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.
