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…

Depth-Aware Machine Learning Framework for Bubble Characterization in Two-Phase Flows
Chaitanya S Nayak, Faizaan Mohammed, Vivek Kumar +2
Understanding the three-dimensional motion of bubbles is essential for interpreting transport and mixing in multiphase flows, especially when bubbles deform under shear or move rap…
