Abstract: Estimates for the three $\alpha$-models known as the LANS-$\alpha$, Leray-$\alpha$ and Bardina models are found in terms a Reynolds number associated with a Navier-Stokes velocity field. They are tabulated for comparative purposes and show clearly that all estimates for the Leray-$\alpha$ model are smaller than those for the LANS-$\alpha$ and Bardina models.
