Flow reorganization and transport enhancement in two-dimensional horizontal convection near a density extremum
Zhiyang Cai, Shengqi Zhang, Kaizhen Shi +2
Horizontal convection serves as a canonical model for geophysical and industrial flows. While the Oberbeck-Boussinesq approximation is well established, the impact of a nonlinear e…

Analytical solutions of layered Poiseuille flows in the diffuse interface model
Jun Lai, Yiming Qi, Lian-Ping Wang
Based on the two-phase macroscopic governing equations in the phase field model, the governing equations and analytical solutions for the steady-state layered Poiseuille flows in t…
