Abstract
The increased demand for renewable energy calls for increased developments to the
techniques of production for such energy. This paper presents a numerical study of conical
collector solar chimney with specific dimensions. A glass spiral of square cross section was
fitted to the collector to investigate its effects on the velocity distribution of air. Results show
that the spiral enhances velocity distribution by (11.57% and 12.82%) corresponding to the
inlet air velocity of (Re=99945 and 499729) respectively. This enhancement will reflect to
the instantaneous electric power which can be produced by such instrument. The
investigation was carried out using CFD program FlUENT14.5, K-ɛ model.
