Experimental Study on the Influence of Bulbous Bow Form on the Velocity Field around the Bow of a Trimaran Using Towed Underwater 2D-3C SPIV

In this study, particle image velocimetry was applied to measure the flow field around bow region of a trimaran with different appendages. The dimensionless axial velocity u/U in test planes 1 and 2 testing model measured by using towed underwater stereoscopic (SPIV) system. Based on data, local sinkage values appendages at speeds 1.766 2.943 m/s were presented. addition, effects speed, bulbous type, T foils, wave studied detail. acquired experimental data help understanding distribution ship bow, can also act as reference verify computational fluid dynamics (CFD) results.
