Abstract: A computational study of the secondary destruction of a drop of organic water-coal fuel (OCWS) in a gas flow was carried out. For the first time, the influence of the temperature of an OCWF drop, which has non-Newtonian properties, on deformation and its further destruction was studied. The computational study was carried out using a numerical technique based on the VOF method, the LES model was used to take into account turbulence, and the technology of adapted dynamic meshes was used to describe the behavior of the interface on the main turbulent scales, which made it possible to resolve secondary liquid droplets up to 20 μm in size. During the work, the shape of the surface of an OCWF drop during the destruction process, as well as the structure of the flow near and in the wake of the drop, were studied. As a result of the calculations, the dependences of the rate of transverse deformation of the midsection of an OCWF drop for different temperatures were obtained. Judging by the results, with increasing temperature, the destruction time of an OCWF drop decreases, which has a beneficial effect on the mixing of OCWF with air.
Keywords: OCWS fuel, secondary destruction of a drop, deformation rate, mathematical modeling, dynamic mesh adaptation technology.
