Prandtl number of lattice Bhatnagar-Gross-Krook fluid
Y. Chen, H. Ohashi, M. Akiyama
Abstract
The lattice Bhatnagar-Gross-Krook modeled fluid has an unchangeable unit Prandtl number. A simple method is introduced in this letter to formulate a flexible Prandtl number for the modeled fluid. The effectiveness was demonstrated by numerical simulations of the Couette flow.
