Rugmini Radhakrishnan 1 Department of Physics, Avinashilingam University for women , Coimbatore -43 Tamilnadu (INDIA) <p style="text-align: justify;">The solar updraft tower is a renewable energy device which uses solar thermal energy to provide upward convective acceleration to the inflow air by greenhouse effect. The hot air rising through the chimney stack drives the turbine and the rotational energy of the turbine is converted into electricity by a generator. The paper presents the design details and performance analysis of a self designed simple and compact demonstration model solar updraft tower made with locally available materials. The model is constructed with the prime aim of understanding chimney concept in experimental studies. Tests were conducted to evaluate the performance of the device by measuring the test parameters updraft velocity, temperature profiles of various junctions and power output. The results obtained indicate that the updraft velocity and power output depend on solar insolation and the height of the chimney stack with a constant collector area.</p> <p> </p> https://ultraphysicalsciences.org/paper/1141/ Solar updraft tower updraft velocity convective acceleration power output chimney concept.
