Experimental Study on Reynolds Number Effects in Propeller Open-water Test Using a Large Cavitation Tunnel

This study investigated the effects of Reynolds number (Rn) on Propeller Open-Water (POW) test results for the KP458 propeller (P/D = 0.7) using the Hanwha Ocean Cavitation Tunnel (HOCT). Tests were conducted under five Reynolds number conditions ranging from 0.35×10⁶ to 1.25×10⁶...

Evaluation of Cavitation and Noise Performance of Composite Propellers for Underwater Vehicles using a Large Cavitation Tunnel

Unlike conventional metallic propellers, composite propellers for underwater vehicles exhibit hydroelastic deformation under operating loads and therefore require evaluation methods that account for both hydrodynamic loading and structural deformation. In this study, model tests...
