Monitoring for Transient Pressures in Pipelines
A change in the flow rate in a full pipeline will cause a change in the pressure within that pipeline. These changes are given careful attention in the well-designed pipeline; however, in the past it has been difficult to accurately measure these transient pressures after the pipeline is constructed and placed in service. Transient pressures exceeding the structural strength of the pipeline wil...
متن کاملNumerical simulation of transient natural gas flow in pipelines using high order DG-ADER scheme
To increase the numerical accuracy in solving engineering problems, either conventional methods on a fine grid or methods with a high order of accuracy on a coarse grid can be used. In the present research, the second approach is utilized and the arbitrary high order Discontinues Galerkin Arbitrary DERivative (DG-ADER) method is applied to analyze the transient isothermal flow of natural gas th...
متن کاملTransient modeling of gas flow in pipelines following catastrophic failure
This paper simulates transient compressible adiabatic gas flows in a long pipeline following a catastrophic failure using an implicit high order finite difference scheme as a discretisation technique for convective terms. A rupture is assumed to be occurred accidentally at a distance from the feeding point of a pipeline where the pipeline being divided into two distinct sections, high and low p...
متن کاملFrequency domain analysis of transient flow in pipelines; application of the genetic programming to reduce the linearization errors
The transient flow analyzing by the frequency domain method (FDM) is computationally much faster than the method of characteristic (MOC) in the time domain. FDM needs no discretization in time and space, but requires the linearization of governing equations and boundary conditions. Hence, the FDM is only valid for small perturbations in which the system’s hydraulics is almost linear. In this st...
متن کاملAlgebraic models of correctness for abstract pipelines
We apply algebraic tools for modelling microprocessors to the specification, implementation, and verification of an abstract pipelined case study. We employ a model of time based on counting events by means of a clock. We model systems by iterated maps that evolve over time from some initial state. We define formal correctness conditions, and introduce the one-step theorems that can reduce the ...
