Detailed Description

Curvature film separation model.

Assesses film curvature via the mesh geometry and calculates a force balance of the form:

F_sum = F_inertial + F_body + F_surface

If F_sum < 0, the film separates. Similarly, if F_sum > 0 the film will remain attached.

Based on description given by Owen and D. J. Ryley. The flow of thin liquid films around corners. International Journal of Multiphase Flow, 11(1):51-62, 1985.
