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.
