Modeling And Dynamic Simulation Of Main Engine Cooling Water System

The main engine cooling water system is an important auxiliary system to ensure the stable operation of main engine. Through the cooling water circulating, the heat that doesn't translate to mechanical energy which distributed away from the running of main engine has been taken away, and it has avoided the metal brittle fatigue and the invalidation of lubricating oil that comes from the accumulation of large number of heat. Therefore, the performance of the main engine cooling water system directly affects the performance of the main engine. If we want to optimize and give full play to the main engine cooling water system performance, there is a need to understand its thermal and hydraulic dynamic process at work. MATLAB is a fashionable tool for computer modeling and simulation. The simulation for main engine cooling water system based on MATLAB embodies the characteristics of tracking, researching, and using new technology, thereby is worthwhileThis paper based on the main engine cooling water system of Dalian Maritime University training vessel, a thermal math model has been founded through the thermal analysis of the heat exchanger and main engine based on the theory of thermodynamics. And based on the theory of fluid mechanics, through analysis of pipeline, the main engine cooling water system hydraulic mathematical model has been founded. Then the author use Simulink for simulating, the result is coincident with known data, thus verifying the correctness of the model.On the basis of the mathematical model is nearly accurately, the author get the simulation displaying through programming language Visual C#. Firstly, utilize the Objected-Oriented Technique to categorize the main engine system into many child objects to achieve certain functions, and compile every object to a class in the programming language Visual C#. These classes are not visual from the outside, and...
