“…Since then many researchers have studied the feasibility of the large scale solar chimney [13,14]. Several pilots of solar chimney have been constructed in the world and their performance has been investigated [15][16][17][18][19]. However, the solar chimney has low conversion efficiency, it compensates for this disadvantage by its cheap, simple technology and low maintenance cost.…”

A B S T R A C TIn this article, a new combination of solar chimney and Humidification-Dehumidification desalination process is introduced. In this system, the air is humidified by injection of water drops into the air flow. Then, the partial of vapors contained in the air is condensed on the outer surface of the cold water tubes. Two mathematical models have been developed for a one-dimensional flow in the solo solar chimney and the integrated system. The performance of the integrated system including power and potable water production is estimated and the results are discussed. Furthermore, it has been demonstrated that increasing in the temperature and mass flow rate of humidifier inlet water would improve the performance of the integrated system. It is found that the increase in water production would cause the decrease in power output. Also, to produce more fresh water, the number of dehumidifier tubes should be increased.

“…In order to obtain comprehensive data on the performance of the solar updraft power plant, data were collected under three different operating conditions (the same procedure that was applied in the case of the Botswana country (Ketlogetswea et al 2008). The air velocity was measured and recorded under the following constraints:…”

“…Solar updraft power plant power plants, with an output of 5-200 MW, require a transparent roof several kilometres in diameter, and the tube has to be as high as possible to achieve a large output. With these of materials of better absorbing radiation, both the diameter of the base of the updraft power plant as well as its height may be substantially reduced (Ketlogetswea et al 2008, Al-Dabbas, 2010.…”

The high cost of importing heavy fuel oil from neighbouring countries of Jordan stimulated the need to consider renewable energy as an alternative to imported power. The paper describes a systematic experimental study on the pilot solar updraft tower power plant model system. Particular attention is given to measurements of air velocity, temperature, solar radiation and voltage difference. This is the first pilot solar updraft power plant that has been built in Jordan to evaluate such technology in Mutah Area. In this paper, all the experimental data were taken from a very small pilot project (compared with other prototypes that we constructed which were placed in the backyard of our faculty). For the experimental part, the solar updraft power plant was a pilot project with an updraft power plant height H = 4(m), updraft power plant radius R c = 0.29(m), plastic solar collector area A coll = 36(m 2 ), collector roof height = 1(m), wind turbine that was a compensation of the suction fan with a diameter D fan = 0.5(m), and a small generator (6 V) The experimental results in this paper show that the maximum height (H max ) gradually increases with the solar irradiation (G). Also, in the same way, with the pressure difference ( p) increases with solar irradiation.

“…A pilot solar chimney system was constructed by Ketlogetswe et al [22] in Botswana, in 2005, which had a glass reinforced polyester chimney with inside diameter of 2 m and height of 22 m with a collection base area of approximately 160 m 2 . They observed that the maximum peak temperature was recorded after the maximum peak irradiation because the ground absorbed part of the incoming solar energy, which was later released.…”

The increased utilization of solar energy has gained the attention of researchers to develop the solar chimney (SC) technology in recent years. Many studies have been conducted in this aear both experimentally and theoretically, whereas experimental studies are mainly focused on small-scale systems. This work provides a comprehensive and updated review that include most of the experimental studies, analytical and simulation works, the solar chimney applications, hybrid systems and geographical case studies based on extended references, citation of the updated works and the specified way of looking at different sections. The technological gaps in differnet sections are identified and a summary of suggestions is given for the future work, including more experimental works on the large-scale systems, and CFD analyses for optimization between the geometrical parameters and the output power. More studies on new applications of solar chimney technology including hybrid systems are also recommended.
