Abstract: This paper investigates numerically the use of a porous rock barrier for the mitigation of the Pv panel. The dust deposition behavior and its influences on the deposition rate for different particle sizes and conditions are analyzed. The CFD method was chosen to predict the dust deposition rates on the PV panel. In doing so, the discrete particle model was applied, while for the turbulent airflow, the k-ω shear stress transport turbulence model with two function profiles defined as UDF at the inlet were employed. We focused on the particle behavior and disposition rate as a function of barrier porosity and distance from the panel. The results indicate that the porosity, as well as the distance between the PV and the barrier, have a significant effect on the particle fluxes. The amount of particles deposited in the panel can be reduced by a rate of 86% for large particles, however, for small particles the reduction in the dust disposition rate is small compared to large ones, reaching 33%. The use of a porous barrier not only helped in terms of particle arrangement but also in terms of vortexes, which disappeared and consequently reduced the particles in suspension upstream of the PV panel. In this regard, we found that 50% is the optimal value.
