abstract = {<p style="text-align: justify;">A front tracking method combined with the real ghost fluid method (RGFM)
is proposed for simulations of fluid interfaces in two-dimensional compressible flows.
In this paper the Riemann problem is constructed along the normal direction of interface
and the corresponding Riemann solutions are used to track fluid interfaces. The
interface boundary conditions are defined by the RGFM, and the fluid interfaces are
explicitly tracked by several connected marker points. The Riemann solutions are also
used directly to update the flow states on both sides of the interface in the RGFM.
In order to validate the accuracy and capacity of the new method, extensive numerical
tests including the bubble advection, the Sod tube, the shock-bubble interaction,
the Richtmyer-Meshkov instability and the gas-water interface, are simulated by using
the Euler equations. The computational results are also compared with earlier computational
studies and it shows good agreements including the compressible gas-water
system with large density differences.</p>},
