| Abstract: | Based on the one - dimensional theory of unsteady flow, the transient flow in cone -shaped pipes is analyzed. Continuity equation and motion equation which can be applied to cone - shaped pipes are obtained and finite difference method for them is brought forward. Contrast and analysis of relative errors are made for numerical results. Based on the results of these analyses, the errors can be effectively decreased as a result of application of the computational method which is presented in this paper. |
