Nowadays surface and underwater vessels with modern propulsion systems and proper
hydro-acoustic performance have been emerged. Pumpjet is one of these new systems …

A numerical model based on a boundary-element method is developed to predict the
performance of flapping foils for the general cases where vorticities are shed near the …

This article comments on the wake model used in moderately loaded rotor lifting line theory
for the preliminary design of propellers and horizontal-axis turbines. Mathematical analysis …

This paper introduced a BEM/RANS interactive method to predict the contra-rotating
propeller (CRP) performance. In the scheme, the forward propeller and the aft propeller are …

The rudder operating in downstream of propeller suffers extra loading induced by propeller
wake. Evolution of propeller wake also can be affected by the rudder especially when the …

The vortex particle method is applied to compute the open water characteristics of marine
propellers. It is based on the large-eddy simulation technique, and the Smagorinsky-Lilly …

We discuss the optimum propeller loading through the use of a lifting line model. Viscous
terms are included through a drag-to-lift ratio, and a hub image model is implemented. Two …

ABSTRACT A novel numerical method solves the VIScous Vorticity Equation (VISVE) in 3D
is presented in this paper. The method was proposed by Tian and Kinnas (2014) in order to …

This article introduces a generalized potential/Reynolds-averaged Navier-Stokes (RANS)
interactive method for the prediction of propulsor performance with an emphasis on the …

Tip-loaded propellers (TLPs) have been shown to increase efficiency by shifting the loading
distribution toward the tip while using a pressure-side winglet to prevent associated losses …
