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 […]
