“…when r KH is the K-H broken particle radius, the shear force is s KH ¼ 3:788B KH K KH X KH : B KH is an empirical constant \ 10, which represents the atomization time of particles; the smaller the value is, the earlier the breakup time is, and the faster the atomization rate is (Patel et al 2015). Then, the particle atomization rate is:…”

To simulate the transonic atomization jet process in Laval nozzles, to test the law of droplet atomization and distribution, to find a method of supersonic atomization for dust-removing nozzles, and to improve nozzle efficiency, the finite element method has been used in this study based on the COMSOL computational fluid dynamics module. The study results showed that the process cannot be realized alone under the two-dimensional axisymmetric, three-dimensional and three-dimensional symmetric models, but it can be calculated with the transformation dimension method, which uses the parameter equations generated from the two-dimensional axisymmetric flow field data of the three-dimensional model. The visualization of this complex process, which is difficult to measure and analyze experimentally, was realized in this study. The physical process, macro phenomena and particle distribution of supersonic atomization are analyzed in combination with this simulation. The rationality of the simulation was verified by experiments. A new method for the study of the atomization process and the exploration of its mechanism in a compressible transonic speed flow field based on the Laval nozzle has been provided, and a numerical platform for the study of supersonic atomization dust removal has been established.

“…The condensation phenomenon of vapor plays an important role in various industries, such as the steam flow and water vapor in nozzles [1], turbines [2], ejectors [3], thermos-compressors [4] and supersonic separators [5][6][7][8][9]. Theoretical and experimental studies have been conducted for the condensation process in supersonic flows, focusing on the nucleation theory, droplet size, latent heat [10][11][12].…”
