    Notes: This paper investigates the application of the centre implicit method for the determination of the pressure transient in a pipeline, and compares the results with those obtained using the method of characteristics and an experimental investigation. The study shows that there are unique values for the stability criterion (ratio of the linear and time increments) and the artificial viscosity term (a damping factor) used in the numerical computation. The time step and the number of nodes required for the accuracy of the method have been considered. The centre implicit method can be readily adapted to transient flow with variable wave speed provided the established conditions are used.

    Two-dimensional analysis of pressure transients in pipelines (1988)
    Chichester : Wiley-Blackwell
    International Journal for Numerical Methods in Fluids 8 (1988), S. 339-349 
    Details
    ISSN: 0271-2091
    Keywords: Computational methods ; Pipelines ; Pressure transients ; Two-dimensional model ; Engineering ; Engineering General

    Notes: The paper presents a two-dimensional model for the investigation of pressure transients in pipelines. The governing equations have been established and a method of solving the equations using the centre implicit method is presented. The theoretically predicted values are compared with the experimentally determined pressure transients for horizontal pipelines with a valve at the end. The two-dimensional model gives results which are accurate than those of the one-dimensional model and are in good agreement with the experimental results.
