摘要
In this paper, the influence of pre-swirling parameters on the performance of the solar vortex power-desalination system is explored on the basis of the established mathematical model and numerical simulation method, to optimize the system performance and provide useful guidance for obtaining the optimal design parameters. The pre-swirl parameters mainly include the number of guide vanes and the inlet pre-swirling angle. The results show that the increase in the number of pre-swirling guide vanes enhances the pre-swirl effect and makes the vorticity distribution more uniform. It also helps to increase the vortex radius and maximum negative pressure in the collector center. However, the increase in the number of guide vanes is not conducive to freshwater production. It will also reduce the momentum of the airflow after pre-swirling, resulting in momentum loss and higher investment cost. The increase in the inlet pre-swirling angle can enhance the swirl effect to a certain extent, but an excessively large inlet angle will lead to excessive resistance, resulting in the appearance of more backflow vortices and the displacement of the vortex center. Hourly fresh water production is hardly affected by the inlet angle.
