Optimizing the collector inlet height of a divergent solar tower using response surface methodology

In this work the response surface methodology (RSM) was adopted to investigate the effect of inlet height of collector on the performance of divergent tower. The traditional computational methods are replaced by RSM to validate the experimental values. The methodology proposed in this work was carried on a 1:60 ratio divergent solar tower with inclined collector experiment model. The collector inlet height was kept constant and the outlet height was varied for three different values. The air properties namely the velocity of the buoyancy air and the temperature at the chimney base were measured using hot wire anemometer and by temperature sensors respectively. The measurement of air velocity and temperature were taken at the three locations. The experimental findings were analyzed to find the optimized geometry for the collector inlet opening height. According to a comparison between the results obtained by the proposed method and the actual model-based global algorithm, the high accuracy and low computation time of the proposed strategy was proved. Also, Optimized value of the inlet opening was determined by RSM. (c) 2021 Elsevier Ltd. All rights reserved.
