Abstract
To better understand performance for high speed surface ships, Reynolds Averaged
Navier-Stokes (RANS) calculations are performed on the Joint High Speed Sealift (JHSS),
which is a monohull concept with four waterjets. The JHSS concept vessel is a long, slender
hull form, approximately 290 m long with a beam of 32 m at full scale. Figure 1 shows the
JHSS hull form and waterjet inlets. Both bare (without waterjet inlets) and powered (with
waterjet inlets) hull forms are predicted and compared with experimental results documented
in Cusanelli et. al. (2007). Computationally predicted quantitative features like sinkage, trim,
resistance and thrust are compared to experimental measurements. In addition to the
quantitative predictions, qualitative features like wave pattern and flow in and around the
waterjet inlets are investigated.
