Some features of the hydraulic mathematical model development for pipeline with variable wall thickness.

摘要

In this paper authors consider a question of the initial data at the stage of the construction of hydraulic model. Some features of the hydraulic mathematical model development for pipeline with variable wall thickness are discussed. Here are presented quantitative assessments of a calculation error of hydraulic models related to different methods of using initial data about the thickness of the pipeline wall. Some experimental results about the effect of non-uniform wall thickness on the hydraulic processes in the pipeline are considered. The method of equivalent diameter identification that takes into account the non-uniform wall thickness distribution is proposed.
