| Abstract: | To meet the need of real time simulation for two phase flow network in power plants, this paper presents a mathematical model based on basic principles and a numerical solution method. This model can be used to describe nonhomogeneous two phase flow networks. The algorithm presented in this paper makes use of the sparsity, the symmetry and the diagonal dominancy of the coefficient matrix to save storage space, reduce computational time and meet the requirements of real time simulations. |
