Abstract: In this paper a new concept of the inertial multiplier is introduced to relax the restriction of the time increment in a computation method for natural gas transient analysis. The range of usefulness of this multiplier and the criteria on the allowable reach length for natural gas transient flow calculation are presented. The validity and the application of the criteria are demonstrated by practical examples. A semianalytical solution with the second-order approximation to the nonlinear difference equations for steady oscillatory flow in natural gas systems is also discussed.
