  Detailed 3-D numerical simulations of an elliptical galaxy orbiting in a
gas-rich cluster of galaxies indicate that gas dynamic stripping is less
efficient than the results from previous, simpler calculations (Takeda et al.
1984; Gaetz et al. 1987) implied. This result is consistent with X-ray data for
cluster elliptical galaxies. Hydrodynamic torques and direct accretion of
orbital angular momentum can result in the formation of a cold gaseous disk,
even in a non-rotating galaxy. The gas lost by cluster galaxies via the process
of gas dynamic stripping tends to produce a colder, chemically enriched cluster
gas core. A comparison of the models with the available X-ray data of cluster
galaxies shows that the X-ray luminosity distribution of cluster galaxies may
reflect hydrodynamic stripping, but also that a purely hydrodynamic treatment
is inadequate for the cooler interstellar medium near the centre of the galaxy.
