Validating Marine Propeller Performance with HELYX CFD
In naval architecture and marine engineering, open-water curves, such as the thrust coefficient, torque coefficient and efficiency as functions of advance coefficient, are the primary hydrodynamic input to propeller and propulsion design. Capturing such quantities accurately through CFD modelling helps engineers take design decisions. This article takes part of our ongoing HELYX Validation and Verification […]
