Effect of Thermal Collector Height and Radius on Hydrodynamic Flow Control in Small Solar Chimney

Summary

A small solar chimney power plant is modelled numerically with a finite-volume solver and the standard k-ε turbulence model to see how collector height and radius shape the airflow. Both dimensions strongly influence flow behaviour and plant performance, with the best case (radius 12.5 m, height 0.25 m) raising the mass flow rate by roughly 27%.
