There are many configuration sizes of the small-scale solar chimney in the world, because of various meteorological and geographic conditions. The main objective of their works is to test the heat transfer performance of the collector and the power output. However, our work is based on the numerical study and numerical optimization of geometric parameters to testing the performance of the prototype with meteorological data. In the first part, we are interested in the experimental characterization of a solar chimney with specific instrumentation. In particular, we present a detailed description of the realization and the various manipulations made to the study. A discussion of results is then presented at the end of this chapter.
