| Abstract: | Through the analysis of the features of the water network in the central cooling system of vessels,the method of applying SIMPLE algorithm to the dynamic simulation of the water network is put forward.The algorithm is then adopted in the actual calculation of water network of vessels.It adopts the method of time stepping.The results of all the time step show the dynamic characteristics of the network flowing.The algorithm,without complex mathematical theory,has simple logic and calculating method.It is easy to understand and program to accomplish,with good convergence. |
