Abstract

The goal of this study is the analysis of the CFD/FSI simulation accuracy of complex shapes with standard CADembedded software packages. In a PLM (Product Lifecycle Management) system, the continuous improvement of CADembedded FSI (Fluid System Interaction) software packages has progressively reduced the necessity for highly specialized external partners. These simulation software packages are designed to keep pace with the unavoidable design development. To make FSI and CFD usable for mechanical designers and design engineers from other engineering disciplines, CFD software package have been largely automated. The specialist expertise required to operate traditional CFD software may be negligible However, the capabilities of CAD-embedded CFD to handle complex geometries and to simulate complex industrial turbulent flows with heat and mass transfer raise question of the accuracy on the results obtainable by a nonspecialized designer. In this paper, a paraglider wing from NASA TN D3442 was used as a case study. This wing was modelled inside commercial CAD software and then thoroughly analysed by using the simulation tools with their default settings. The accuracy of results was then evaluated. © 2006-2015 Asian Research Publishing Network (ARPN).
