A computational and an experimental study on the effect of the chimney height on the thermal characteristics of a solar chimney power plant

What is it about?

The aim of this paper is to highlight the impact of the chimney height on the local characteristics of the air flow within a solar chimney power plant (SCPP). The SCPP prototype was numerically and experimentally investigated. The experimental prototype of the SCPP was built in the National School of Engineers of Sfax, University of Sfax, Tunisia in the North Africa. The prototype is characterized by a collector diameter equal to D=2750 mm, a collector height equal to h=50 mm, a chimney height equal to H=3000 mm and a chimney diameter equal to d=160 mm. The air flow has been simulated using the commercial software Ansys Fluent 17.0 and the computational findings have been validated using our experimental results. CFD (computational fluid dynamics) findings confirm that the chimney height is very influential on the local characteristics of the SCPP.
