In this paper the viscous flows around a mathematical SWATH in full scale are simulated based on the computational fluid dynamics commercial software FLUENT. The numerical results of total pressure, wall shear stress and the corresponding viscous resistance coefficient at different velocity are obtained. The computational viscous resistance coefficients are compared with the estimated ones using empirical formula. The validity of the software to predict the three dimensional viscous flows and viscous resi...
