Summary
A two-dimensional steady-state CFD model in ANSYS CFX tests how tapering a solar chimney toward its top affects airflow through a ventilated cabin, across several bottom-to-top width ratios. The narrowest outlet produces the highest exit velocity, yet the uniform straight duct delivers the most air changes per hour, so convergence lowers overall chimney performance.
