A RANS Modelling Approach for Predicting Powering Performance of Ships in Waves

A RANS Modelling Approach for Predicting Powering Performance of Ships in Waves
A RANS Modelling Approach for Predicting Powering Performance of Ships in Waves
In this paper, a modelling technique for simulating self
propelled ships in waves is presented. The flow is modelled
using a RANS solver coupled with an actuator disk
model for the propeller. The motion of the ship is taken
into consideration in the definition of the actuator disk region as well as the advance ratio of the propeller. The
RPM of the propeller is controlled using a PID-controller
with constraints added on the maximum permissible RPM
increase rate. Results are presented for a freely surging
model in regular waves with different constraints put on
the PID-controller. The described method shows promising
results and allows for the studying of several factors
relating to self propulsion. However, more validation data
is needed to judge the accuracy of the model.

Abstract

In this paper, a modelling technique for simulating self
propelled ships in waves is presented. The flow is modelled
using a RANS solver coupled with an actuator disk
model for the propeller. The motion of the ship is taken
into consideration in the definition of the actuator disk region as well as the advance ratio of the propeller. The
RPM of the propeller is controlled using a PID-controller
with constraints added on the maximum permissible RPM
increase rate. Results are presented for a freely surging
model in regular waves with different constraints put on
the PID-controller. The described method shows promising
results and allows for the studying of several factors
relating to self propulsion. However, more validation data
is needed to judge the accuracy of the model.
