Abstract

One of the ways to generate power from the solar energy is to use the solar chimney technology. In the present study, by examining the weather map of Iran and using GIS software for selecting the appropriate area for the power plant site, the four physical models proposed studied for the solar chimney. This study is a numerical simulation (by MATLAB) regarding four physical models of solar chimneys in the city of Bam site, in Kerman province. The difference between the four mentioned models of the solar chimney is in storage system and the use of air diffuser. The behaviors of all four models were examined according to the valid meteorological information on a specific day from the target site. According to the results of the simulation, which includes airflow speed in several internal parts of the chimney and the production capacity of each of the mentioned models, the best and most proper model of solar chimney can be selected for the studies site and a proper estimation of the final production can be obtained.

Highlights

  • The quantity of energy consumption has significantly increased with the advancement of technology and industrialization of countries

  • Solar Chimney Power Plant is one of the new projects that will always be a place for innovation and research, and so far, general research has been done on this type of technology in Iran, but so far, no detailed study has been done due to the weather conditions in a specific place in Iran

  • In Eq (8), the efficiency of the solar chimney power plant is obtained with the multiplication of the whole efficiency where ηch is the efficiency of the chimney, ηT is the efficiency of the turbine and ηg is the efficiency of the generator

Summary

INTRODUCTION

The quantity of energy consumption has significantly increased with the advancement of technology and industrialization of countries. We consider the country's climate maps to find an ideal site over a 25-year period in terms of cloudiness, temperature, sunlight and wind intensity for establishing a site for Solar Chimney Power Plant [10]. Studies on this case have rarely been done in the Iranian climate. In order to reach the best and most proper place in Iran to establish the Solar Chimney Power Plant site, we need to study the desired parameters, such as the amount of sunlight, the amount of cloudiness in the area and the intensity of the wind. Parts of Kerman province and South Khorasan province are the most sunlight radiated regions of Iran based on the least cloudy days
