Numerical Simulation of the Collector Angle Effect on the Performance of the Solar Chimney Power Plant
...Show More Authors

Sloped solar chimney system is a solar chimney power plant with a sloped collector. Practically, the sloped collector can function as a chimney, then the chimney height can be reduced and the construction cost would be reduced.The continuity, Naver-stockes, energy and radiation transfer equations have been solved and carried out by Fluent software. The governing equations are solved for incompressible, 3-D, steady, turbulent standard model with Boussiuesq approximation  to develop for the sloped solar chimney system in this study and evaluate the performance of solar chimney power plant  in Baghdad city of Iraq numerically by Fluent (14) software with orking conditions such as solar radiation intensity (300,450,600,750 and 900 W/m2), and collector which angle (0°, 15° and 30°).The results show that the change of collector angle has considerable effects on the performance of the system.The velocity increases when the collector angle increases and reach to the maximize  value at a collector angle (30°). The temperature increase with the collector tile angle increase at solar intensity times (7:30,8:15,9,10 AM) but decrease at 12:30 PM) corresponding to solar intensitIes. The study show that Iraqi wather are suitable for this system.

Topic Management in Selected Dementia Patients' Speeches: A Clinical Discourse Analysis Study

Topic management is the awareness of how speakers deal with initiating, developing, changing, and ending a topic and how they fix the relationship when a misunderstanding occurs. It is such an important unit of conversation as it includes the transition from one strategy to the other to be accomplished in a systematic and orderly manner. These strategies are impaired in dementia patients thus lead to communication breakdown. This study aims at detecting the dementia patients' topic management strategies in selected speeches and answering the questions of which of these strategies are fully or partially detected in these speeches. The researchers use a qualitative method to examine the speeches of those patients and they adopt an eclectic
