Computation of Hydrodynamic Characteristics of A Marine Propeller Using Induction Factor Method Based on Normal Induced Velocity

A Study on Effects of Blade Pitch on the Hydrodynamic Performances of a Propeller by Using CFD

“…The problem was investigated by using the finite volume method of ANSYS-FLUENT in which the fundamental equations are the continuity equation and the RANS (Reynolds-Averaged Navies-Stocker) equations in moving reference frame written as follows [1][2][3][4][5][6][7][8][9][10][11][12].…”

“…The third and fourth terms are due to the unsteady change of the rotational speed and linear velocity, respectively. These terms vanish for constant translation and/or rotational speeds [1][2][3][4][5][6][7][8][9][10][11][12].…”

“…Therefore a systematic study of controllable pitch propellers and the effects of pitch ratio on controllable propeller characteristics is thus essential in order to seek crucial design guidance for enhancing the operational efficiency of the propeller. The most popular reports on controllable pitch propeller that had been published in recently years are researching on hydrodynamic characteristic of marine propeller and controllable pitch propeller of a ship by developing a numerical simulation method or using [4][5][6][7][8]. Others reported on the effects of blade pitch, shape, profile of D DAVID PUBLISHING blade and optimization of a blade pitch for the controllable pitch propeller [1,2,9,10].…”

CFD results on hydrodynamic performances of a marine propeller

“…The significant results were that the normal induced velocity of a propeller can be obtained simply and accurately by means of the induction factor. The vertical theory based on Biot-Savart law was used to find the induction factor, then the hydrodynamic characteristics of the propeller were estimated [6]. In addition to this area, the important results of simulating, analyzing and optimizing the characteristics of a marine propeller were presented by Hu J. et al, (2017), Lin Y. et al, (2017) and Wang Z. et al, (2012), [7][8][9].…”
