Abstract
The chimney junction of a Solar Chimney Power Plant (SCPP) is the main element connecting
the solar collector to the chimney, significantly impacting the SCPP design by altering the
airflow direction. This study utilized the numerical code "Ansys Fluent" to investigate how the
chimney junction radius affects local airflow characteristics. The results showed that the local
airflow characteristics and therefore the SCPP efficiency were significantly impacted by changes
in junction radius. Additionally, the influence of these parameters on air turbulence in the
transition zone was analyzed. The results demonstrated that changes in the junction radius
significantly impacted local airflow characteristics and, consequently, the efficiency of the
SCPP. Furthermore, the maximum velocity inside the chimney varied and shifted its location
with changes in the junction radius. These factors directly affect the overall turbine performance,
influencing both structure and power capacity
