STUDY OF THE DYNAMICS OF THE TEMPERATURE FIELD IN A HIGHLY VISCOUS HYDROCARBON MEDIUM UNDER THE INFLUENCE OF ELECTROMAGNETIC RADIATION
The authors of the article propose the mathematical model of the dynamics of the temperature field in a high-viscosity hydrocarbon medium under the influence of electromagnetic radiation. The mathematical model based on heat conduction equation written in cylindrical coordinates. The dissipation of the electromagnetic field energy is modeled by the introduction of the density of distributed heat sources, which depends on the emitter power. The convective heat transfer is taken into account by introducing the effective thermal conductivity coefficient, which is calculated by the empirical proportion. The dimensionless analysis of the mathematical model is conducted. The problem is solved numerically by the method of control volumes according to the implicit scheme. The software tool was created and the comparison of simulation results with experimental data was carried out. The need to take account the heat loss in the degassing of hydrocarbon liquid with increasing temperature of the medium is shown.
