Authors Fraggedakis D., Pavlidis M., Dimakopoulos Y., Tsamopoulos J. Abstract We examine the abrupt increase in the rise velocity of an isolated bubble in a viscoelastic fluid occurring at a critical value of its volume, under creeping flow conditions. This ‘velocity discontinuity’, in most experiments involving shear-thinning fluids, has been […]

Authors Chatzidai N., Dimakopoulos Y., Tsamopoulos J. Abstract According to linear theory and assuming the liquids to be inviscid and the bubbles to remain spherical, bubbles set in oscillation attract or repel each other with a force that is proportional to the product of their amplitude of volume pulsations and […]
