5.4.4.2 Turbulent Regime (Distorted Bubbles)

We now consider the turbulent interfacial drag force,

(5.45)

but we leave the definition of the distorted bubble drag coefficient for later. At this point we make the momentum equation dimensionless in terms of the drag coefficient. Following the method of the previous section, the RHS of the momentum equation becomes,

(5.46)

where . For the condition the velocities obtained for the kinematic condition, , become

(5.47)

and the kinematic wave speed is
