Aerodynamic shape optimization of a low drag fairing for small livestock trailers [PDF]

open access: yes, 2008
Small livestock trailers are commonly used to transport animals from farms to market within the United Kingdom. Due to the bluff nature of these vehicles there is great potential for reducing drag with a simple add-on fairing.

Aerodynamic Shape Optimization Using Automatic Adaptive Remeshing [PDF]

open access: yes, 1997
This work presents a new methodology base on the use adaptive mesh refinement (AMR) techniques in the context of shape optimization problems analyzed by the Finite Element Method. A suitable and very general technique for the parametrization of the optimization problem using B-splines to define the boundary is first presented.
