A Lattice BGK Model for Viscoelastic Media

Yue Hong Qian, Yue Fan Deng

Research output: Contribution to journalArticlepeer-review


A two- and three-dimensional lattice Bhatnager-Gross-Krook model is proposed to simulate viscoelastic media. Large-scale equations are derived using the Chapman-Enskog expansion. A simple linear relationship between the parameter E which is introduced to characterize the elastic behavior and the transverse velocity is obtained. Numerical simulations further confirm the analytical predictions.
