Formulation of the Reynolds equation on a time-dependent lubrication surface [PDF]
, 2016 The Reynolds equation, which describes the lubrication effect arising through the interaction of two physical surfaces that are separated by a thin fluid film, is formulated with respect to a continuously evolving third surface that is described by a ...
