Recent reviews of Milky Way globular cluster formation indicate three groups associated with the formation of the bulge, disk and halo, and one group associated with accretion processes (van den Bergh 2000). Malinie et al. (1991) showed that the metallicity distribution of the halo globular clusters can be reproduced in the ELS scenario if the initial density profile is nonuniform and kinetic feedback from supernovae is taken into account. Their simulations were performed in 1D and did not include dark matter. In this study, using an N-body/SPH simulation, we attempt to explain the effect of stellar feedback on the formation and distribution of the halo globular clusters. We present 3D simulations of a rotating homogeneous collapse including dark matter, cooling gas, and stars. Three formulations of supernova feedback are considered.
