We show that the behaviour of the pressure and saturation depends crucially on the behaviour of the separation h (t, x, y) among the two surfaces. In particular, we exhibit some simple formulations for which we prove (rigorously) that a cavitation region is formed instantaneously (even for initially saturated flows). Some numerical experiences are also given.engjournal articlehttp://www.sciencedirect.com/science/article/pii/S1631072106001458http://www.sciencedirect.com/restricted access517.954517.97lubricationcavitationElrod-Adams modelReynolds equationfree-boundary problemsEcuaciones diferenciales1202.07 Ecuaciones en Diferencias
