| Abstract: | By analyzing the topology of circulating water systems and the operating characteristics of two-speed pumps,a model for hydrodynamic calculation of circulating water systems was built,with which output parameters of the system were obtained under varying conditions using Matlab and C++ mixed programming.Taking a certain supercritical power unit as an example,optimize the cold end system of its manifold two-speed circulating water pump on above basis.Results calculated with the model can be used to find the ... |
