Mass-Transfer Control With Microbubbles in Highly Turbulent Decaying Flows
Vivek Kumar, Prasoon Suchandra, Jason Rom +3
We hypothesize that combining extreme turbulence with a minute reduction in surface tension (surface tension of the liquid) using surfactant provides a simple and scalable rout…
Impact of the formation angle on the drag of bio-inspired -formations
Prasoon Suchandra, Shabnam Raayai-Ardakani
Bio-inspired flight formation is a well known technique for energy saving among groups of fixed-wing aircraft, and as of recently, for groups of quad-rotors. Here, we s…
Laminar-to-Turbulent Transition of Yield-Stress Fluids in Pipe and Channel Flows
Shivam Prajapati, Prasoon Suchandra, Vivek Kumar +3
We present direct numerical simulations (DNS) of laminar to turbulent transition in Herschel-Bulkley (HB) yield-stress fluids flowing through pipes and rectangular channels. The si…
Bubble coalescence dynamics in a high-Reynolds number decaying turbulent flow
Vivek Kumar, Prasoon Suchandra, Ardalan Javadi +2
This study experimentally investigates bubble size evolution and void fraction redistribution in an unexplored, coalescence-dominated regime of decaying turbulent bubbly flow. The…
