DESIGN OPTIMISATION OF AN UNMANNED UNDERWATER VEHICLE

Journal of Engineering Science and Technology, 2007
The results of fluid flow simulation around an unmanned underwater vehicle (UUV) are presented in this paper. The UUV represents a small submarine for underwater search and rescue operation, which suits the local river conditions. The flow simulation was performed with a commercially available computational fluid dynamics package, Star-CD.
