Joint High Speed Sealift (JHSS) Appendage Resistance Computation Fluid Dynamics (CFD) Analysis

摘要

The appendage drag of the surface ship. Joint High Speed Sealift (JHSS), has been estimated by various empirical methods with drag coefficients for the separate appendage components. These empirical methods have been shown to be inaccurate when the interaction between appendage components is considered. Recently, several existing methodologies for the existing appendage drag were reviewed. In this study, Computational Fluid Dynamics (CFD) using the Reynolds Averaged Navier-Stokes (RANS) equations was chosen to perform drag analysis on several configurations with different turbulence models. A breakdown resistance contribution list for all the appendage elements is also provided in this study.
