Which 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.
