The Hydrodynamic Performance Prediction of Ship Hull with Propeller

Abstract

This paper describes the hydrodynamic performance prediction of ship hull with propeller by using CFD techniques. As an attempt in investigating the flow features around ship hull equipped with a rotating propeller, open water test, resistance test, and self-propulsion test were conducted. The paper discusses also the applicability of different turbulence models which are used to predict the hydrodynamic performance of the propeller, the hull, and the interaction hull-propeller. The hydrodynamic performance prediction method was gotten and was validated. The computational results were validated against the existing experimental data.

CFD-Based Study on the Airflow Field in the Crushing Chamber of 9FF Square Bale Corn Stalk Pulverizer

“…The specific boundary types are shown in Table 2. Because the hammer rack and hammer blades in the crushing chamber are rotary components, and others belong to a static area, therefore, the method of the Moving Reference Frame [19][20][21] was adopted to find the solution and specify the type of continuous medium on the mesh models, which are rotary region and static region, and the medium type is Fluid.…”

On Propeller Performance of DTC Post-Panamax Container Ship

“…For instance, Shen et al have investigated the hydrodynamic performance of a ship with a propeller numerically. They have used RANSE with CFD and validated their solutions with the existing experimental data [3]. Tocu and Lungu predicted the hydrodynamic performance of a ship hull with a propeller [4].…”
