AB - <p style="text-align: justify;">We analyze in this paper the pressure splitting scheme of a partitioned semi-implicit
coupling algorithm for fluid-structure interaction (FSI) simulation. The semi-implicit
coupling algorithm is developed on the ground of the artificial compressibility
characteristic-based split (AC-CBS) scheme that serves not only for the fluid subsystem
but also for the global FSI system. As the dual-time stepping procedure recommended
for quasi-incompressible flows is incorporated into the implicit coupling stage, the
fluctuating pressure may be unusually susceptible to the AC coefficient. Moreover, it
is not trivial to devise an optimal AC formulation for pressure estimation. Instead,
we consider a stabilized second-order pressure splitting scheme in the AC-CBS-based
partitioned semi-implicit coupling algorithm. Computer simulation of a benchmark
FSI experiment demonstrates that good agreement is exposed between the available
and present data.</p>
