Coupling Two-Phase Fluid Flow with Two-Phase Darcy Flow in Anisotropic Porous Media

This paper reports a numerical study of coupling two-phase fluid flow in a free fluid region with two-phase Darcy flow in a homogeneous and anisotropic porous medium region. The model consists of coupled Cahn-Hilliard and Navier-Stokes equations in the free fluid region and the two-phase Darcy law in the anisotropic porous medium region. A Robin-Robin domain decomposition method is used for the coupled Navier-Stokes and Darcy system with the generalized Beavers-Joseph-Saffman condition on the interface between the free flow and the porous media regions. Obtained results have shown the anisotropic properties effect on the velocity and pressure of the two-phase flow

Cross-listings and dividend size and stability: evidence from China

We investigate the relationship between cross-listings and dividend policy. We find that Chinese cross-listed firms have lower and more stable dividends than their non-cross-listed peers, and that dividends become more stable the longer a company has been cross-listed. We also find the strength of the cross-listing/dividend policy relationship varies based on the market where the shares are cross-listed. The strength of the relationship varies from B-shares (least strong) to Hong Kong shares (stronger) to American Depository Receipts (strongest). Our results indicate cross-listings may influence both dividend size and stability, and that this influence can vary by the type of cross-listing
