Griffith correlation

Brief

The Griffith correlation is an empirical correlation which defines:

• The boundary between the bubble and slug flow.
• The void fraction of gas in bubble flow - gas hold up H_G.

Math & Physics

The bubble flow exist when:

$\frac{q_g}{q_g + q_L} < L_B$

The gas holdup:

$\frac{q_g}{q_g + q_L} < L_B$
