Interaction Effect on Hydro-dynamic Performance of a Rudder - Propeller System
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 4
Abstract
The use of Computational Fluid Dynamics (CFD) to predict internal and external flows has risen dramatically in the past decade. The widespread availability of engineering workstations together with efficient solution algorithms and sophisticated pre - and post-processing facilities enable the use of commercial CFD codes by graduate engineers for research, development and design tasks in industry. In the ocean engineering in which the cost of experiment is dramatically high, or sometime the experimental method is impossible to employ, it becomes the vital tool in designing and optimizing the shape of vessels and propulsion. In this topic, authors used the commercial software, ANSYS-Fluent v.14.5, to illustrate the effects of rudder and propeller on hydrodynamics performances of the marine propeller. The first objective of the paper uses the numerical method to analyze and build the characteristic curves of marine propeller. The second aim is to study how the rudder affects the hydrodynamic feature of the propeller in ship operation. The marine propeller used in this work has designed conditions as follows: the diameter of 3.65m; speed of 200rpm; average pitch of 2.459m; boss ratio of 0.1730. Using the CFD, the characteristic curves of the marine propeller and others CFD results as well as pressure, velocity distribution around propeller and efficiency of the propeller are presented. From result of comparison at other CFD results, the interaction effect on hydro-dynamic performances of the rudder – propeller system is investigated. The obtained outcomes of this paper are the significant foundation to calculate and design of an innovative kind of propulsion for ships with high performances.
