Numerical simulation of the oil pipeline temperature field for the thermal method of measuring the thickness of paraffin deposits taken into account of oil movement

The article provides an analysis of the problems of precipitation of asphaltresin-paraffin deposits on the inner surface of the walls pipelines. The problem of numerical modeling of the temperature field of the heated oil pipeline in the ANSYS software product is considered. The process of heating and cooling the pipeline at different sediment thicknesses and oil velocities is investigated. A two-dimensional numerical model of the oil pipeline has been developed, which allows studying the behavior of its temperature field during heating and cooling. The research developed in the article helps to reduce the cost of maintaining oil pipelines.
