Power generation in the laboratory conditions by solar chimney: Model study

In this study, solar chimney systems which are one of the methods of obtaining electricity from solar energy systems were examined. In the method of solar chimney, the rays from the sun heats the air starting from the ground in the painted black ground and around the chimney. Heated air on the ground and around is directed to the chimney by means of special pipes. This flow of warm air inside the chimney due to the vertical direction serves as a wind tunnel. This air flow rotates the vertical axis perpendicular to the propeller placed in the appropriate sizes and numbers.It is possible to make use of the each of the propellers on an axis system with the help of dynamo electric current injury. In this experimental study, supported by the project and laboratory conditions, a comprehensive study on electrical energy production out of solar chimney method was carried out: In this study, a controlled wind is formed as a result of creating maximum temperature difference between the two ends of the chimney by means of heating the ground by creating artificial solar chimney and at the same time cooling the end of it.The velocity of the air before hitting the propeller was increased by using conic ends through the exits of the chimney.With the help of the black hoses laid over greenhouse area, and with additional heating, the chimney was provided to work longer.The changes in the velocity of the air flow which form in the chimney were examined by means of using the pipes which are in different sizes and by increasing the area of the greenhouse.With the help of the propellers that are attached to the engines placed in different parts of the chimney,the values in the digital multimeter were fettered and the parameters that affect the system?s performance were determined.As our experiment is different from the ones applied in the literature and because we have determined our system?s efficiency according to the theoretical calculations,the efficiency seems to be lower.Our study is a pioneer for the prototype which will be carried out in naturel conditions.It is proposed that in Diyarbakır, larger systems can be established to produce continuous electricity with the help of solar chimney method in naturel conditions.
