  Based on the bag model, we revisit the deconfinement phase transition under
rotation. On top of the usual rotational energy for noninteracting particles,
we perturbatively analyze the revolution effect of the hadron bag, i.e., of the
potential confining quarks. The revolution effect can be phenomenologically
translated into the rotational correction to the QCD vacuum energy or the gluon
condensate. We demonstrate that if the revolution effect is (is not) taken into
account, the transition temperature increases (decreases) as the angular
velocity increased. The `revolving bag model' provides a feasible explanation
of the recent lattice simulations, contrary to effective models, showing that
rotation favors the confined phase.
