Hydrodynamic measurements on the Joubert hull in the AMC cavitation tunnel with CFD determined blockage corrections
The Joubert generic submarine geometry and its derivatives are currently the subject of computational studies in over six countries interested in comparing simulation techniques for diesel electric submarine hulls. This paper presents the second set of flow measurements at comparable and higher Reynolds numbers to the existing available measurement set. This new data set allows increased confidence in the use of the Joubert generic submarine geometry for Computational Fluid Dynamic (CFD) studies.
Measurements were taken in the Australian Maritime College’s (AMC) cavitation tunnel on the hull of a 1:52 scale generic bare hull Joubert submarine model, oriented at zero degrees incidence. Surface pressure and skin friction measurements were collected at a range of Reynolds numbers. Boundary layer velocity and turbulence intensity surveys were performed at a number of positions aft of the hull. A wake survey was taken at the propeller plane for the bare hull with, and without, the aft control surfaces.
The hull’s cross sectional area created an 8.5% solid blockage ratio in the test section. Blockage corrections were performed using CFD simulations of the bare hull as mounted within the test section and additionally in a low blockage domain. The results from these two CFD domains were used to provide full field blockage corrections to the measurements.
