The paper deals with the verification of three pipeline models: the non-linear distributed parameters model, the linear distributed parameter model and the linear lumped parameters model. All the models were comparatively verified on the basis of the measurements on a real pipeline.

The problem of modelling and simulating pipelines that are used for transporting different fluids is addressed in the paper. The problem is solved by including fluid density in the model beside pressure and velocity of the medium. First, the system of nonlinear partial differential equations is...
