Currently, Russia is actively building new wind farms. The issues of studying physical processes are relevant, as the existing wind farms have an impact on the microclimate and ecology. In wind farms, the appearance and movement of liquid and solid particles is possible. In the study of two-phase flows containing a suspension of aerosol particles (dispersed phase) in the carrier medium (dispersion medium) in the atmosphere, it is important to choose the main parameters that determine the system correctly and adequately describe the real process using the formulated mathematical model. The work is devoted to the development of new solvers based on the SOWFA library as part of the open-source OpenFOAM 2.4.0 package for the study of particle dynamics modeling in the atmospheric boundary layer and in the model wind farm.
The Euler-Lagrangian approach is used to describe particle dynamics. Two new solvers based on ABLSolver and pisoTurbineFoam.ALM have been developed to simulate particle dynamics. The calculation results for the case of a neutral boundary layer and a model wind farm with 14 model wind turbines are presented. Graphs for the distribution of particles with different diameters in height are given. Between 72 and 96 cores were used to calculate one example.
