In this study, a simulation for two story building associated with vertical solar chimney was made by using ANSYS 2022/R1. The study conducted under the climatic conditions of Al-kut city/ Iraq on 5/8/2016. involved comparison between ventilation performance SC before and after adding Energy Storage. Al-dura, RT-42, block-shaped paraffin wax were three types PCM that studied in order to find op...

This paper presents an optimization of a solar chimney power plant with an inclined collector roof using genetic algorithms. Five design parameters that affect the system performance are the collector radius, collector inlet height, collector outlet height, chimney height and diameter. A multi-objective design to simultaneously optimize three conflicting objectives including system efficiency, ...

We studied the behavior and residual structural capacity of reinforced concrete chimneys subjected to an uncontrolled fire. We used a combination of a heat transfer finite element model – to obtain the temporal distributions of temperature during the fire event – and the structural model of concrete chimney design provided by the American Concrete Institute (ACI 307–08). This approach allows es...

Abstract Solar chimneys have been intensively studied as an effective method for natural ventilation of buildings. Though numerical methods, such Computational Fluid Dynamics (CFD), widely utilized in studies, they usually require extensive computational resources. Moreover, experimental study is quite complicated and costly. In recent years, machine learning has started to be used a tool the t...
