Abstract

A dynamic model of a contacting mechanical seal for down-hole tools, operating in the mixed lubrication regime, has been constructed. Two dynamic cases are examined: the behavior of the seal after it is subjected to a nonequilibrium initial condition and the behavior of the seal as it tracks axial runout of the rotating face. In both cases the seal experiences much larger leakage and inflow (incursion) rates than under steady-state conditions, although in the former case the duration of the increased rates is very short.
