PROCESSING THRUST OF NUMERIC SIMULATION RESULTS FOR MARINE VESSEL HULL-PROPELLER USING STAR-CCM+ SOFTWARE

Abstract

The marine vessel thrust forces receiving from the hull-propeller numeric simulation by the STAR-CMM+software present digital arrays in real time with the variable time step. The thrust force signals were processed: (a)-Selecting an array from the simulated array with the good conregence; (b)-resampling with the fix minimal step dt for the selected array; (c)-calculating the average cycle vector from the made cycle vectors of the thrust force from the resampling arrays in the b-task;(d)-resampling with NFFT=2^k samples of the received vector in the c-task; (e)-making FFT for the resamled array. The MV. Fortuner Navigator (VOSCO) was verified for studying the propeller’s thrust. The software for data processing was coded in LabView.
