Numerical Simulation of Vortex Breakdown by the Vortex-Filament Method

Numerical simulation of fully nonlinear interaction between steep waves and 2D floating bodies using the QALE-FEM method

This paper extends the QALE-FEM (Quasi Arbitrary Lagrangian-Eulerian Finite Element Method) based on a fully nonlinear potential theory, which was recently developed by the authors ([1], [2]), to deal with the fully nonlinear interaction between steep waves and 2D floating bodies. In the QALEFEM method, complex unstructured mesh is generated only once at the beginning of calculation and is move...

Investigating the effect of using a Lateral duct in the body of a floating breakwater by numerical method

Floating breakwaters are good alternative to the so-called fixed base breakwaters, which, in addition to having the main purpose of protecting the beach from waves, also maintain the water connection between the sea and the protected area. Researchers in order to increase the efficiency and increase the performance range of floating breakwaters, have done many researches on their effective para...

Nonlinear Coupling Motion Numerical Simulation of Freely Floating Body and Sloshing

Nonlinear interactions among incident wave, tank-sloshing and freely floating body coupled motion are investigated. The fully nonlinear sloshing and body-surface nonlinear free surface hydrodynamics is simulated using a non-uniform rational B-spline higher-order panel method (NURBS) in time domain based on the potential theory. A robust and stable improved iterative procedure, iterative semi-im...

Vortex Method Simulation of Ground Vehicle Aerodynamics

Recent results are presented from the application of a grid-free vortex method to the prediction of turbulent aerodynamic flows produced by road vehicles. The approach has the character of a large eddy simulation and incorporates a fast technique for evaluating the mutual interactions of several million vortex elements needed in describing the dynamically significant structure of the turbulent ...
