“…In the present study, curve fitting was conducted for the simulations results of the solar chimney turbine in previous section. Von Backström and Gannon [31] investigated the off-design performance of a solar chimney turbine; they suggested that the ideal solar chimney turbine characteristic curve (load coefficient versus flow coefficient) is a straight line. The load and flow coefficients are defined as w ¼ DH= 1 2 U 2 and u ¼ V z =U, respectively; where DH, U and V z are the enthalpy drop across the turbine, the blade circumferential velocity and the air axial velocity, respectively.…”

“…They also investigated the performance of the turbine using an experimental program and showed total-to-total efficiency and total-to-static efficiency of 85%-90% and 75%-80%, respectively. Later on, in 2004, von Backstrom and Gannon [79] presented analytical equations to show the influence of each coefficient on the turbine efficiency, designed the turbines of the solar chimney, and determined the preliminary turbine layout according to the turbine efficiency. A typical schematic turbine layout is shown in Fig.…”

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.

“…Total-to-total efficiencies of 85-90% and total-to-static of 77-80% over the design range were measured. (Von Backström & Gannon, 2004) presented analytical equations in terms of turbine flow and load coefficient and degree of reaction, to express the influence of each coefficient on turbine efficiency. Analytical solutions for optimum degree of reaction, maximum turbine efficiency for required power and maximum efficiency for constrained turbine size were found.…”
