Numerical modelling of the process of thermal treatment of oil slime

This article proposes modelling processing oil waste to minimise the harmful impact on the environment. The available research is limited to one-dimensional models. The novelty of the work lies in the new mathematical and numerical model of convective heat-mass transfer in oil slime. The mathematical two-dimensional model is constructed that describes heat and mass transfer during the evaporation of harmful substances from the oil slime. The numerical solution of this mathematical model is based on the alternating directions implicit (ADI) method. The calculations were carried out for comparison with experimental data of other authors at different temperatures of 150degree celsius, 250degree celsius, 450degree celsius, and at speeds of 0.83 m/s, 1.6 m/s, and 2.7 m/s. The calculation results obtained correctly describe the processes of heat and mass transfer during the thermal treatment of oil slime. For interactive user analysis of oil-slime processing, a software application has been developed using Python software tools.
