In order to observe the influence of the wake behind the propeller on the rudder, this paper conducts an interference experiment on the propeller-rudder system using the B4–55 propeller and the NACA0020 marine rudder, and analyzes the hydrodynamic characteristics of the rudder behind the propeller wake. The computational domain is divided into a rotational domain and a fluid domain, and the domain is discretized using cut-cell meshes. The discrete equations are solved using the k − ε model. The rotation motion of the propeller is simulated by using the slip grid. Data information is transferred through the interface to complete the hydrodynamic performance simulation of the propeller system. This paper analyzes the hydrodynamic performance of marine rudders under different rudder angles, and explores the influence of the propeller on the resistance, lift and limit rudder angle of the rudder. The distribution characteristics of the velocity field and pressure field in the computational domain were analyzed.

摘要

In order to observe the influence of the wake behind the propeller on the rudder, this paper conducts an interference experiment on the propeller-rudder system using the B4–55 propeller and the NACA0020 marine rudder, and analyzes the hydrodynamic characteristics of the rudder behind the propeller wake. The computational domain is divided into a rotational domain and a fluid domain, and the domain is discretized using cut-cell meshes. The discrete equations are solved using the k − ε model. The rotation motion of the propeller is simulated by using the slip grid. Data information is transferred through the interface to complete the hydrodynamic performance simulation of the propeller system. This paper analyzes the hydrodynamic performance of marine rudders under different rudder angles, and explores the influence of the propeller on the resistance, lift and limit rudder angle of the rudder. The distribution characteristics of the velocity field and pressure field in the computational domain were analyzed.
