Sažetak
This paper represents a continuation of the research work related to the further development of the alternative renewable energy concept of the solar plant with short diffuser (SPD). The main idea of the alternative energy concept is to produce and maintain vortex system in the controlled conditions from available renewable energy source. Finally, produced pressure difference by the vortex system will ensure usefully shaft work to drive the turbines. Already developed numerical model of the SPD concept was further upgraded taking into account the effect of the guide vane geometry on the vortex stability and shape. Different blade shapes were examined (variation of the geometry) as well as different configurations of the attack angles. Finally, it was found that novel enrolled and proposed geometry modifications have a significant effect on the minimal required delta pressure for establishing and maintaining the vortex, while at the same time keeping the maximal velocities in reasonable range with respect to the present technical limitations in the case of the turbines.
