A Novel Approach of Unit Conversion in the Lattice Boltzmann Method
Round 1
Reviewer 1 Report
LB is bridging the macroscopic scale (represented by continuum based models) and the miscroscopic scale represented by particle dynamics models. While the simulations uses normalized lattice units, applications are often requiring physical units. The manuscript shows a comprehensive collection of equations. The method is based on the Redlich-Kwong equation of state.

Below fig. 1, the intention of multi phase systems with different properties is discussed, e.g., water with density1000 kg/m³, air with density 1.23 kg/m³. How is the proposed conversion method to be applied on such systems? Can it be discussed, possibly in the conclusion section?
-
Eq. (2) is the Redlich-Kwong equation of state (doi: 10.1021/cr60137a013). The authors should discuss the applicability of this equation, e.g., according to Murdock (1993) ISBN 978-0-8247-8808-7. The R-K EoS seems to be applicable for p/p_c < T/(2T_c). https://en.wikipedia.org/wiki/Redlich%E2%80%93Kwong_equation_of_state

Below eq. (10): [18] should be cited as Wolf-Gladrow [18], it is a compound name.
