    The solar chimney power plant (SCPP) is an economical technology for the production of solar electricity. The increase in the production efficiency of this type of installation is depended of the several theoretical and experimental studies. This paper studied the effect of some key parameters such as (ambient temperature, solar radiation), on the performance of the solar chimney power plant. Using the dimensions of our SCPP prototype and also compared by the Manzanares prototype with Ouargla weather conditions. Where the maximum solar radiation and ambient temperatures are 957 W/m2 and 30 ° C at 15h00. Respectively. The measured average air speed is 1.04 m/s, and the electric power value of the prototype is 2.04W. The results show that the solar radiation and the ambient temperature have a direct effect in the SCPP efficiency, and also confirm that the technology of solar chimneys is the best solution to install in the hot and arid areas like Ouargla city.

    Parametric Study of the Effective parameters on the Performance of Solar Chimney Power Plant
    (جامعة الوادي - university of el oued, 2021-06-25) Nouar, Hadda; Azizi, bdelghani; Chiba, Younes; Tahr, ,Toufik
    The solar chimney power plant (SCPP) is an effective option for electrical energy production from solar energy. In this paper, a numerical model to predict the SCPP performance is developed. The effects of collector angle and solar radiation are investigated on the parameters of air as the velocity and temperature. The study shows that when the collector angle is 20°, the velocity maximum is 1.8 m/s at the chimney base and the maximum temperature is 332.1k. in addition, increased solar radiation produces an increase in temperature (from 400 w/m² to 900 w/m²) and air velocity (from 22.25 m/s to 2.75 m/s) in the solar energy tower
