Evaluation of Air Thermodynamic Performance Indicator of Different Designs of Solar Vortex Chimney

Abstract

This research focused on integrating two modern updraft system technologies, namely solar vortex technology and solar chimney technology, in order to test a simulation system for three proposed models and compare their speed and thermal energy performance, using the ANSYS 2022 R1 program. At the same time, the proposal of these three models is regarded as a system development, with previous research serving as a foundation. Choosing the optimal angle for the guide blades and the number of blades. Three speeds were tested using the ANSYS 2022 R1 program (0.6, 0.9, 1.2) m/s. Simulations of the three proposed models were compared, and it was discovered that the shape of the air vortex in the first model, which consists of a vortex motor and a perforated glass casing, is more regular than in the second and third models, The results showed that the speeds and resulting energy for the suggested models were close, but the initial model had the highest speed (2.418) m/s and energy (2.340 J), When selecting the entry speed (0.9) m/s followed by the second and third models, respectively.
