Abstract. This work offers the opportunity to examine the possibility of implementing a solar chimney power plant in the region of M'Sila (Algeria) whose solar potential is exceptional. The solar chimney is a generator of electricity starting from solar energy. Performance analysis of a solar chimney which has similar characteristics to prototype Manzaneres (Spain), that could produce 39-72 kW, and that would be used to supply electricity to 39 000 -72 000 inhabitants, was performed using the software fluent. The results obtained are very promising.

A solar chimney PV/T power plant (SCPVTPP) is proposed. Mathematical models are established for the PV/T solar collector, the chimney, and the power conversion unit, respectively. Performances of the designed SCPVTPP are then simulated. The SCPVTPPs with different PV module areas are finally discussed. It is found that the PV cells hold the highest temperature in the solar collector. Temperature rise of the PV module has significant influences to its power generation. Without cooling, the PV power capacity has an average decrease of 28.71%. The contradictory influences of temperature rise and airflow cooling lead to an 11.81% decrease of the average power capacity. By adding the power generated by PVT, the total PV-related power contribution increases by 4.72%. With the increase of the solar collector ratio, the temperature rise and the wind velocity both first decrease then increase, the SCPP power productivity decreases linearly, and the PV power productivity increases linearly, whereas the PVT power productivity first increases linearly then increases superlinearly. There is a reversed solar collector ratio, exceeding which the PV generates most power. In this study, solar thermal power takes the major role when the solar PV area ratio is smaller than 0.055.

“…Bernardes and Von Backström, (2010) undertook the study of the performance of two models of chimney. Larbi et al, (2010) presented an analysis of the energy performance of a solar chimney in the strongly sunny region of Adrar (south of Algeria); it may provide up to 140-200 kW of electricity throughout the year. Moreover, Chergui et al, (2010) have developed a CFD model compatible with the Benchmark of Vahl Davis, (1983) for natural convection.…”

The study of thermal and ventilation parameters, obtained in a transient, laminar solar chimney of reduced dimensions, (1 < m <3) m with a square collector (side = 2m) is presented. Experimental measurements has been made to determine the temperature of the absorber and the fluid in the collector, it is shown that at the entrance of the chimney, the temperature of the absorber decreases slightly while that of the fluid is maintained at a maximum level. Temperature differences were observed up to 32°C between the atmosphere and the fluid in April. A temperature variation at the absorber depending on the stack height is presented. Temperature measurements in the chimney, at various heights depending on the axial coordinate, show a variable temperature profile. It is, from these, shown that, in the selected interval of stack height, the average speeds of output increase linearly as a function of stack height. For a chimney of 3m in height and 20cm in diameter, a maximum speed of approximately 0.7 ms -1 was observed. The lack of appropriate equipment handicaps the velocity measurement at the chimney entrance. Thus, the results of simulations with the computer code COMSOL 5.1 has confirmed temperature values measured at the chimney entrance and after this, velocity values are determined.
