Computer software system for determining the pressure field resulting from hull flow and operation of the marine propeller

Abstract

In the paper CISAKU software system for calculating the pressure field resulting from hull flow and operation of the marine propeller is shortly described as well as a thorough analysis of calculation results obtained by means of it. An influence of the secondary wave system, water depth and bottom-reflection coefficient, fluid viscosity and propeller operation on the pressure field around the hull, as well as influence of propeller operation on the acoustic pressure field is presented. The system’s theoretical background was already published in the previous issue of this quarterly.
