Past analyses have left several unanswered questions regarding the operation of a pumping ring seal. This paper addresses some of these unresolved problems. In particular, treatment of the film-ring interfacial boundary condition and the return portion of the pumping cycle are numerically investigated. Further, a simple model is proposed to determine whether or not the seal operates fully flooded.
