On the basis of the equation describing wall effect during the motion of a solid sphere in non-Newtonian power—law fluids, an analogical equation was formulated for bubbles and adopted for the motion in a centrifuge taking into consideration bubble size changes during the motion. The experimental verification confirmed the equation validity in the range d/D < 0.2.
An equation was formulated for the calculation of gas bubble velocity under the centrifugal force in a viscoplastic body described by the Herschel - Bulkley equation. The experimental verification confirmed the validity of the equation but only in a great enough distance from the point where the bubble lasted immobilized despite the buoyancy force.
