Analysis and Validation of a Designed Solar Chimney with 50 KW Output Power between 7 AM and 5 PM during a Year as a Power Supply Unit for Bushehr Province, Iran

Abstract

The aim of the current research is analysis and validation of a solar tower (chimney) designed for power generation in southern provinces of Iran, especially in Bushehr province. The analysis consists of preparing and drawing the graphs of solar irradiance intensity on horizontal planes, analysis of solar tower without storing, preparing graphs considering the diameter of collector (absorber or receiver), height of tower and diameter of turbine in 50 kW output power. Already, the amount of received solar energy is computed by available relationships governing on tower elements as a set of codes in MATLAB. In addition, experimental data is already used to validate the results obtained from finite element software FLUENT. In the current research, the obtained results from graphs produced by computer softwares (EXCEL and FLUENT) with 50 kW daily output power (from 7 AM to 5 PM during a year) are analyzed and validated comparing to the model produced in Manzanares, Spain. The obtained results are represented in two parts: the first one shows characteristic curve of solar towers (i.e. a curve representing the relationship between tower elements in a given power); the second part shows the variable output power during a day. It is obvious from characteristic curves that in low powers and small diameters, turbine needs large size receiver and high equivalent height. Considering the cost effectiveness conditions, it can scientifically compete with the produced model
