2. Gümbel's hypothesis is extended to allow 2D treatment in conjunction with computation

3. The two-component rupture front description of the cavitated fluid film; 1.0 > ΘΣ > 0.0 is an unknown parameter. ΘΣ < ! 1.0 would yield the asymptotic Swift-Stieber state. 4. In 1D problems, a universal post-incipience cavitation evolution is τ-stepped according to

5. In 2D problems, it is necessary to specify lubricant circulation roles of the two bearing ends:
