Unsteady Conjugate Numerical Simulation of the Solar Chimney Power Plant System with Vertical Heat Collector

Summary

A solar chimney power plant that merges the chimney and a vertical heat collector, with a paraffin phase-change storage layer, is modelled in Fluent under time-varying solar radiation. Airflow speed and power rise with irradiance, peaking at noon around 122 W, while stored heat keeps a small output going overnight and performance improves over successive days of operation.
