Numerical Assessment of the Resistance of a Solar Catamaran in Shallow Water

In this paper, a numerical assessment of the effect shallow water on total resistance solar catamaran SolarCat is carried out using computational fluid dynamics within software package STAR–CCM+. The unsteady viscous flow was modelled based Reynolds-averaged Navier–Stokes (RANS) equations with application k−ω SST (k−ω Shear Stress Transport) turbulence model. RANS were discretized by finite volume method, and position free surface determined method. conditions, mesh morphing algorithm applied. Numerical simulations for deep limited depths corresponding to h/T=7.6, h/T=4, h/T=2 at two speeds. verification study uncertainty calculated sinkage catamaran. A detailed analysis around out.
