← ScienceWhich outcome occurs when volatile liquid boils rapidly in microfluidic channel?
A)Critical heat flux limit is surpassed✓
B)Surface tension enhances fluid stability
C)Laminar flow fully develops upstream
D)Viscosity decreases at channel entrance
💡 Explanation
When a liquid boils rapidly in microfluidics, nucleation causes vapor bubbles. These generate a heat flux; surpassing the critical limit leads to dryout because heat transfer declines drastically rather than increasing or remaining stable.
