Wheeled armored vehicles (WAVs) are designed for military applications, but they are frequently used in special disaster relief missions during floods caused by severe global climate change. To tackle threats arising from environmental change, developing WAVs with amphibious functions will inevitably become a trend in the future. The purpose of this study is to investigate the hydrodynamic performance of WAVs. An existing WAV model is adopted as a starting point, and computational fluid dynamic (CFD) techniques are used for performing analyses. This study analyzes the relationship between the configuration of a WAV and the sailing resistance. Two computation modes are associated with CFD used for flow simulation around the vehicles: the relative motion and absolute motion computation modes. The results of the simulations obtained through these two modes have been discussed and compared to develop an efficient tool for performing hydrodynamic performance analysis of amphibious wheeled armored vehicles (AWAV).
