Abstract

The paper explores the use of the Local Correlation Transition (LCTM) RANS model capable of predicting transition to turbulence in application to underwater glider performance prediction. Validation of the method is established by analysing the flow past SD7003 and SD8020 hydrofoil sections and comparing with experimental data. Finally, flow past a swept wing suitable for use on an underwater glider is predicted. The results indicate significant improvement in capturing the flow physics in comparison to a standard shear stress transport (SST) k-omega model. Three-dimensional effects are found to play a significant role in the flow behaviour due to the significant sweep of the foil considered.
