Kandlikar Microchannel Formulation:
• Confinement Number: Co = (1/Dh) √(σ / (g (ρL − ρV))) > 0.5
• Boiling Number: Bo = q″ / (G · hfg)
• Two-Phase HTC: htp = max( hNBD, hCBD ) [W/(m²·K)]
• Wall Temperature: Twall = Tsat + (q″ / htp) [°C]
• Confinement Number: Co = (1/Dh) √(σ / (g (ρL − ρV))) > 0.5
• Boiling Number: Bo = q″ / (G · hfg)
• Two-Phase HTC: htp = max( hNBD, hCBD ) [W/(m²·K)]
• Wall Temperature: Twall = Tsat + (q″ / htp) [°C]

📘 Calculation Methodology & Microchannel Boiling Standards
Kandlikar Microchannel Correlation
Incorporates confinement effects ($Co$) and boiling number ($Bo$) to capture transition between nucleate bubble nucleation and thin-film evaporation:
htp = max( hNBD, hCBD )
Confinement Number Criterion
When $Co = \frac{1}{D_h}\sqrt{\frac{\sigma}{g(\rho_L - \rho_V)}} > 0.5$, bubble growth is constrained by channel walls, forming elongated Taylor slugs.
Key Engineering Assumptions
- Parallel rectangular microchannel heat sinks with uniform flow distribution.
- Saturated two-phase flow boiling regimes ($0.05 \le x \le 0.85$).
- Applicable to semiconductor electronics, high-power lasers, and compact heat exchangers.
