A model of two incompressible Newtonian fluids coupled across a common interface is studied. The nonlinearity of the coupling condition exacerbates the problem of decoupling the fluid calculations in each subdomain, a natural parallelization strategy employed in current climate models. A specialized partitioned time stepping method is studied which decouples the discrete fluid equations without sacrificing stability and maintaining convergence. This is accomplished through explicit updating of… 
Schwarz domain decomposition methods for the fluid-fluid system with friction-type interface conditions
Abstract In this paper we consider a fluid-fluid system coupled with a friction-type interface condition which is described by a jump of the velocities along the tangential interface. Based on domain
Error estimates of a decoupled algorithm for a fluid-fluid interaction problem
It is proved that under a restriction on the time step scale, the convergent orders for the velocities in H 1 norm and for the pressures in L 2 norm are optimal and the decoupled algorithm's error estimates are optimal.
