This paper reviews development of turbulent non-isothermal round jet flow in pit oil. Increasing requirements for environmental protection challenge the oil industry to minimize the oil spill accidents throughout the production and transportation processes. Hydrodynamic interaction of pit oil with flow is in reasonable agreement with data of industrial tests. The authors prove law of development turbulent non-isothermal jet flow in pit oil. In this paper a mathematical model was designed and numerical simulation of turbulent non-isothermal flow in pit oil was performed. The mathematical method is based on the non-isothermal fluid flow in pit oil using solution of Reynolds-averaged Navier-Stokes equations and equations of the k-symbol model of turbulence. The developed model has been validated with experimental data. Numerical simulation calculation results were found to be in reasonable agreement with data obtained from the experiments. Turbulent (molar) transfer is important in flow part and vortex zone of reverse flow. In the other part convection and molecular mechanism of momentum and heat transfer dominated. The developed mathematical model and numerical simulation methods are used to study the process of heating pit oil by hot fluid flow. In technical aspect it allows to determine the mass of heated pit oil which is used in thermo-mechanical technology of gathering spilled oil.
