Comments to 'Simple explicit formulae for calculating limit dimensions to avoid undercutting in the rotor of a Cycloid rotor pump'

摘要

I want to express a general appreciation for the deep analysis of our paper [1], which has been made by the authors of paper “Simple explicit formulae for calculating limit dimensions to avoid undercutting in the rotor of a Cycloid rotor pump”, but I wish also to observe that unfortunately the formula and the presented methodology based on profile curvature radius are not original and new as Ye et al. claim.
