The two-dimensional laminar flow in a long squeeze film damper with constant circular precession is solved numerically for increasing values of the squeeze film Reynolds number. For the full film solution and a fixed orbit radius, the calculated inertia and damping force coefficients increase as the squeeze film Reynolds number increases. The results presented show the significant effect of fluid inertia on the dynamic force response of squeeze film dampers operating with large Reynolds numbers. © 1988 Taylor & Francis Group, LLC.
