On one numerical method for transport

Optimal control, prevention and investigation of accidents and detection of discrepancies in estimated gas supply and distribution volumes are relevant problems of trunkline operation. Efficient dealing with these production tasks is based on the numerical recovery of space-time distribution of non-isothermal transient flow parameters of transported gas mixtures based on field measurements in a substantially limited number of localities spaced considerable distances apart along the gas pipeline. The paper describes a practical method of such recovery by defining and solving a special identification problem. Simulations of product flow parameters in extended branched pipelines, involving calculations of the target function and constraint function for the identification problem of interest, are done in the 1D statement. In conclusion, results of practical application of the method in the gas industry are briefly discussed.
