The program package PPLN for calculation of a nonstationary gas flow in pipelines
The package consist of computation modules permitting to calculate the
flow parameters at any instant of time in the following pipeline
elements: pipe, branching, local drag of different type (hydraulic, pipe
bending, washer, steel framework), receiver, valve; the drag coefficients
being taken from reference books. For the every given system of
pipelines a controlling program is worked out which realizes the
computation of all pipeline elements in a given sequence. A perfect
gas or superheated steam or saturated steam with condensation or real
gas taken into account can be considered as a work body. The
computation algorithm is based on the Godunov difference scheme. The
package can be employed for a wide range of pressure, temperature and
velocity of a gas.
