Computational solutions of sloshing phenomena in density stratified fluids in triangular shaped containers with the vertex of the container in the downward direction were investigated. Two of the typical cases are reported in this paper. The Navier-Stokes equations in terms of vorticity and stream function were solved by applying a second-order finite-difference computational method. A nearly two-layered continuously stratified fluid system is examined to investigate the motion of the pycno-cline that separates the lighter upper fluid from the bottom heavier fluid. The tilted side walls alter the sloshing significantly; in some cases vortex projectiles are ejected as the waves interact with the sidewalls.
