Abstract:
This work presents a comparative experimental study of the thermal performances of two types of solar chimneys. The objective is to compare the thermal performances of a solar chimney with a hyperbolic collector associated to a plane absorber painted black. We used a second collector a collectors equipped with hemispherical concentrators. To do this, we designed an experimental device at the central maintenance workshop of Ouagadougou ‘s University. Measurements carried out on the device with the hot wire anemometer, a data logger and a pyranometer allowed us to conclude that the device with hyperbolic collectors associated with hemispherical concentrators is more advantageous than that with a plane absorber in terms of thermal performance. From these results, we show that the temperature and speed of the air change depending on the amount of sunshine.
