    Allowance for the deformation of the drop surface on the evaporation process
    (2018) Bushmanov, V. M.; Kogut, V. E.; Khmelnuk, M. G.; Gihareva, N. V.
    There are a number of problems for the solution, which need to solve the problem of evaporation of liquid droplets. This problem has been solved many times in various ways. However, these solutions use certain assumptions: the drops are solid inelastic spheres, there is no coagulation, deformation of the drop. Because of what the quality of calculation suffers and there can be a difference in calculations and experimental data. In order to increase the quality of calculations, we have attempted to add corrections to the calculations that correct certain shortcomings. The evaporation of the drop is affected by a number of factors. Among them, the properties of substances between which the exchange takes place such as the density of surface tension, heat capacity, as well as their temperatures and relative velocities of the media. The droplet, when moving through the atmosphere, experiences friction against the air, which causes the liquid to move inside the drop.

    Efficiency of refrigerating ejector systems for condensation of liquid hydrocarbons of oil products
    (2017) Butovskyi, I. D.; Kogut, V. E.
    The simple traditional methods of prevention of losses of oil product having the low cost (the respiratory valve, gas-leveling system) are insufficiently effective. The known basic approaches of storage of oil products by introduction of superficially active agents. However, in practice these ways have not found broad application. Essential source of economy of oil resources - elimination of losses at their production, processing, transportation and storage. By estimates of specialists, only at the expense of it it is possible to receive up to 20% of all economy of fuel and energy resources. Damage caused by these losses consists not only in reduction of fuel resources and cost of the lost products, but also in negative ecological effects which are result of environmental pollution by oil products. Therefore, fight against losses of oil products gives not only economic effect, but also is vital for ensuring conservation.
