Flow onset for a single bubble in yield-stress fluids
Ali Pourzahedi, Emad Chaparian, Ali Roustaei +1
We use computational methods to determine the minimal yield-stress required in order to hold static a buoyant bubble in a yield-stress liquid. The static limit is governed by the b…

Bubble clouds in viscoplastic fluids
Emad Chaparian, Ian A. Frigaard
Viscoplastic fluids can hold bubbles/particles stationary by balancing the buoyancy stress with the yield stress. In the present study, we investigate a suspension of bubbles in a…
