The solar chimney power plants (SCPP) are thermodynamic devices that transform the heat produced by the solar radiation into electricity. A SCPP make significant contributions to the energy generating in countries where sunlight is available. The optimization of the solar setups is essential to enhance their economic profitability. In this article, a numerical method is investigated by the use of the commercial CFD code Ansys Fluent to analyze the airflow within the solar chimney. Different considered cases have been studied. Indeed, a new design of the SCPP is presented and compared with a conventional solar chimney power plant (CSCPP). The proposed design is characterized by a convergent collector output. For each case, the local flow characteristics were presented and discussed. This technical solution favorite the generated power of CSCPP. This article is identified important to increase the generated power for an existing SCPP.

Abstract-Using renewable energy is one of the most promising paths towards the sustainable development, especially in oil dependent economy nations like Iran. In present study, recourses, status and prospect of solar energy in Iran was investigated. Among renewable energy sources, Iran has a high solar energy potential with more than 300 clear sunny days in a year and average 2300 kW-h solar radiation per square meter. Considering just 1% of the total area with 10% system efficiency for solar energy harness, about 9 million MW h of energy can be obtained in a day. Iran had a plan to install 53,000 MW capacity plants for electricity generation. The existing small capacity solar energy plants are in provinces of Shiraz, Taleghan, Yazd, Semnan, Khorasan and Tehran. Based on the specified available solar through technology, solar area, average solar hours and average solar direct irradiation, the technical potential of solar electricity was estimated to be 14.7 TWe. The share of RES in total installed electricity capacity is expected to be about 2% in 2030. It is expected that the cumulative RES installed electricity capacity will reach 2800 MW in 2030 and it needs more than 2800 million US dollar investment among 2010-2030.

In the paper, a numerical and experimental investigations on a prototypal solar chimney system integrated in a south facade of a building is presented. The chimney consists of a converging channel with one vertical wall and one inclined. The numerical analysis is carried out on a three-dimensional model in airflow and the governing equations are given in terms of k-ε turbulence model. The problem is solved by means of the commercial code Ansys-Fluent. The numerical analysis was intended to examine the effect of the solar chimney's stack height and depth. Results are given in terms of wall temperature distributions, air velocity and temperature fields and transversal profiles for a uniform wall heat flux on the vertical wall. Thermal and fluid dynamics behaviors are evaluated in order to have some indications to improve the energy conversion system. Furthermore first results of an experimental investigation on a chimney system 4.0 m high and 1.5 m wide are given. Air velocity in the channel and surface temperature on the heated wall are presented.
