文摘
- •
Drag-reducing CTAC solution flows on heating plate was experimentally studied.
- •
Fluid functionality depends on temperature, local shear rate, and CTAC concentration.
- •
Destruction and recovery conditions of micellar-network structures were estimated.
- •
We used effective structural number of micelles to link HTR to fluid flow condition.
- •
Minimum structural number for functionality was proposed as percolation threshold.
