Experimental Analysis Modelling of Tower Solar Chimney

Solar Tower Chimney (STC) is one of the sustainable sources. The experiment aims to study the effect of different air temperatures (ambient temperature) on the airflow inside the chimney as well as on the power generated by (STC) during the summer period and the possibility of installing tower solar Chimney in Basrah region. The experiment results show that the power produced by the chimney will increase per hour when the outside temperature increases. In the present work, different values of the air velocity inside the chimney (height 7.2 m) were measured, the maximum was reached at 2:00 pm (2.9 m/s) afternoon when the ambient temperature was 45.8 C°. The absorbing surface effect is discussed. It was noted that the high level of humidity and the excessively flying dust on most days of the year are considered to be the most important determinants of this type of system. The present study included developing a simplified mathematical model depending on the conservation of energy and mass for the present solar chimney.
