“…Li. J-y et al [127] evaluated the influences of collector radius and chimney height on the power output of SCPP using a theoretical model that has been verified by the experimental data of the Spanish prototype. The theoretical power output of an SCPP was reported to be directly proportional to the collector radius and chimney height 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.

“…Kasaeian et al [5] presented a comprehensive review of solar chimney systems. Depending on the research directions, solar chimneys may serve various goals [6][7][8][9], such as natural ventilation in the buildings [2,5,[10][11][12][13], small-scale power plants, generation in full-scale energy generation systems, and some applications in smart islands [14][15][16][17][18].…”

In this, paper the authors propose a new simplified method of solving the problem of air flow through a solar chimney system using a classical system of equations for the principles of conservation (momentum, mass, and energy), as well as a general solution to research the problem using similarity theory. The method presented in this paper allows one to design a solar chimney. The theoretical analysis was compared with experimental studies on existing solar towers. The experimental and theoretical studies were satisfactorily consistent. For clarity, the phenomenon of heat flow in the solar chimney was described using dimensionless numbers, such as the Reynolds, Grashof, Galileo, Biot, and Prandtl numbers. In the equations for the dimensionless geometric parameters, the ratios of the collector radius to the thickness gap, height, and chimney radius were used. The method used to test the system of equations allows us to analyse various solar collectors easily. In the scientific literature, there is a lack of a simple calculation method to use in engineering practice, suitable for each type of solar chimney independent of dimensions and construction parameters.

“…Furthermore, Mehran Ghalamchi [6] constructed a proto type for solar chimney and he changed the inlet dimension and he found that as the height of the inlet decrease the air film temperature increase which leads to increase of inlet velocity to 1.3 m/s. In addition to experimental studies, several numerical researches [7][8][9][10][11][12][13][14] have been conducted to model the experimental work and make enhancement on the simulated model. Ramon Molina Valle [7] made a mathematical model based on (Navier-Stokes and Energy Equations) using Finite Volumes Method in Generalized Coordinates.…”

“…In addition, Jing-yin Li [11] made a numerical model by using Runge Kutta [12] method to simulate the experimental data of the Spanish prototype and this model found that there is a restriction on maximum collector radius, beyond which the attainable power output of the solar chimney increases very slowly. On the contrary, no such restrictions was placed on the chimney height exists.…”

In the current study, potential improvements in both flow field and heat transfer characteristics of a prototype solar chimney for power generation through passive flow control approaches have been numerically examined. The numerical modeling was conducted for three different schemes to enhance the velocity magnitude at the entrance of the chimney. The first scheme is concerned with the effect of the number of turbulent generators on the maximum flow speed obtained while the second scheme deals with the effect of throat area at the entrance of the chimney. The last scheme is related to investigating the effect of making round edges having different radii at the entrance of the chimney.
