Abstract: Abstract: A finite volume method based Cartesian grids is adopted to solve the Navier-Stokes equations using Improved Delayed Detached Eddy Simulation turbulence model with OpenFOAM for the study the 3D evolution as a large depression internal solitary wave propagates across a vertical cylinder. Numerical results reveal that these significant differences of density and kinematic pressure are found at both sides of the cylinder and the complex vortex is occurred around the cylinder because of partially transmission and reflection effect. Moreover, the kinematic pressure difference may maintain a maximum as the radius is over the critical value in the same physical condition.
