TY - JOUR TI - Variational principle for a generalized Rabinowitsch lubrication AU - Ma Hongjin JN - Thermal Science PY - 2023 VL - 27 IS - 3 SP - 2001 EP - 2007 PT - Article AB - This paper adopts Rotem and Shinnar’s modification of the Rabinowitsch fluid model for the one-dimensional non-Newtonian lubrication problem, a variational principle is established by the semi-inverse method, and a generalized Reynolds-type equation is obtained. This article opens a new avenue for the establishment of Reynolds-type equation of complex lubrication problems.
