NUMERICAL SIMULATION OF BOTTOM SOIL SCOUR NEAR PIPELINES
The report presents the results of numerical simulation of the process of bottom soil scour near the pipeline under the influence of fluid flow. The problem is considered in a 2D statement, fluid - laminar, soil - uniform and incoherent. To solve the problem finite element method is used. As a result of solving the problem pictures of flows emerging next to pipelines are obtained, depth of soil scour is determined depending on the flow rate, the initial depth of the pipeline and soil characteristics.
