摘要: A self-developed laser image measurement system was established to study the behavior of
bubble for-mation at a single orifice in non-Newtonian polyacrylamide (PAAm) solutions.
Images of bubbles were captured by a CCD camera and volumes of bubbles were digitally
analyzed online. The effects of rheological property of PAAm solution, orifice, reservoir,
and gas flowrate on bubble formation were studied experimentally. It is found that the
volume of bubble increases with the concentration of PAAm solution, the diameter of the
orifice, and the gas flowrate, respectively, whereas little effect of reservoir is observed
in experiments.
