Comment on the paper Li-Shi Luo, Wei Liao, Xingwang Chen, Yan Peng and Wei Zhang, Numerics of the lattice Boltzmann method: Effects of collision models on the lattice Boltzmann simulations, Physical Review E 83, 056710 (2011)

Critical comments on the entropic lattice Boltzmann equation (ELBE), by Li-Shi Luo, Wei Liao, Xingwang Chen, Yan Peng and Wei Zhang, Physical Review E 83, 056710 (2011), are based on simulations which make use of a model that, despite being called ELBE by the authors, is in fact fully equivalent to the standard lattice Bhatnagar-Gross-Krook equation. As a result, the conclusion of Luo et al on ELBE is circular, hence devoid of scientific bearing.
