Design method of ship cabin ventilation under coupling factor feature extraction
To address the issue of ship cabin ventilation design considering only a single factor without considering the characteristics of other factors,which affects the efficiency of ship ventilation,a coupled factor feature extraction method for ship cabin ventilation design is studied.Consider the ship cabin ventilation system as a coupled system,introduce informa-tion criteria,and use Newton's method to extract key coupling factor characteristics that affect the ventilation effect of the ship cabin.Based on the feature extraction results of coupling factors,a mathematical model of the ship cabin ventilation sys-tem is constructed using knowledge components to ensure smooth air circulation in the cabin.Select computational fluid dy-namics software to simulate the ventilation situation of ship cabins.Based on the simulation results,perform calculation ana-lysis,adjustment,and optimization of ship cabin ventilation design,obtain design indicators such as ventilation mode and air exchange rate of the ship cabin ventilation system,and determine the final ship cabin ventilation design scheme.The experi-mental results show that the ship cabin ventilation system designed using this method meets the requirements of air ex-change rate,and the reduction in air supply and exhaust volume is significant,effectively improving the ventilation effi-ciency of the ventilation system.
