       Hydrodynamic Optimization Using Integrated CFD Tools

 School of Computational Sciences,George Mason University

Computational simulations are making significant contributions 
to many important areas of naval hydromechanics.  Computational 
fluid dynamics (CFD) in particular is proving to be extremely 
useful in submarine and ship design.  This seminar will present 
an integrated hierarchy of CFD tools for ship design and hull-form 
optimization.  The following related subject would be discussed,
  * Toolkit for practical design and hull form optimization, 
    including CAD and automatic unstructured grid generators;
  * Three linear-potential-flow methods for predicting the flow due 
    to a ship advancing in waves and far-field wave patterns;
  * An near-field flow calculation method based on Euler equations, 
    unstructured grid, and finite element method for large-scale 
    ship-flow simulation;
  * Hydrodynamic optimization of a trimaran using a simple CFD 
    solver and a gradient-based optimization technique.

The future outlook of hydrodynamic optimization will also be addressed.
