THREE-DIMENSIONAL SIMULATION OF HEAT AND MASS TRANSFER PROCESSES DURING SHF HEATING OF OIL FLOW IN A PIPELINE

This article considers mathematical simulation of heat and mass transfer processes in the course of SHF heating of flow of a viscous fluid, oil included, in a pipeline. A specific feature of the mathematical model is account for three-dimensional effects, for example, the dependence of volumetric and surface heat release sources on the polar density angle. A numerical solution is obtained by the method of finite differences. The results of calculations for a concrete problem of SHF heating of oil flow in a pipeline are given. The results of two-dimensional and three-dimensional models are compared, and the influence of a number of factors on the results of simulation is analyzed.
