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 HG.

Math & Physics

The bubble flow exist when:

 \frac{q_g}{q_g + q_L} < L_B [1]

The gas holdup:

 \frac{q_g}{q_g + q_L} < L_B [1]
