Computational Fluid Dynamics CFD

Advanced analysis techniques involving Computational Fluid Dynamics (CFD) may provide increased understanding of the response to design conditions.  Under extreme conditions such as breaking waves, extreme winds or complicated geometries, CFD provides a mechanism to optimize multiple scenarios resulting in cost effective solutions. 

The example represents an unsteady 3D fully nonlinear/non-hydrostatic simulation of turbulent mixing within a channel and the impact of a baffle on the horizontal mixing characteristics.  Complicated geometries maybe included into the simulation using existing 3D CAD models.  

Estimation of breaking wave loads across near shore structures is an immensely complicated problem.  Computational fluid dynamics and a numerical wave tank may provide further knowledge of the loading patterns including uplift and overtopping pressure distributions.  This example shows the breaking wave distribution over a series of wave protection devices.  

For each structure, a time history of pressure can be derived leading to improved structural mitigation measures and design approaches.
