Simulation and applications of the ship central cooling system in DMS2016 marine engineering simulator

Based on the analysis of the structure and mechanism of the ship cooling water system and the modular modeling method, the mathematical model of the cooling water system suitable for real-time simulation calculation is established, and the pipe network calculation is used to obtain the flow and each pipe's node pressure. The simulation data of the ship cooling water system are obtained by using Visual C ++ programming software, and the accuracy of the mathematical model is verified by comparing the simulation data with real ship data. The mathematical model can be used to describe the flow distribution, pressure variation and heat transfer in the ship cooling water system. The distributed visual simulation system interface developed by object-oriented technology is used to realize the dynamic operation of the cooling water system and ensure the simulation accuracy. The system has been successfully applied to DMS2016 large-scale marine engine simulator, and used in the crew teaching and training, and achieved significant results.
