Abstract
Gas turbines are considered essential components in generating electricity, as they are characterized by their high efficiency and ability to meet the increasing demand for energy. However, these turbines face major challenges that affect their performance, most notably the effect of ambient temperatures, especially in hot regions, which leads to a decrease in compressor efficiency and thus a reduction in production capacity. Therefore, it is necessary to adopt effective strategies to improve cooling and enhance performance. This research aims to study the effect of using a mist cooling system mixed with Nanofluids containing AL2O3 particles in enhancing the cooling efficiency of gas turbines. Three different concentrations of Nano fluids, namely 1.5, 2, and 2.5%, were tested to evaluate their effectiveness experimentally. The results showed that using a 2% concentration improved the cooling efficiency by 28.99%, while a 1.5% concentration resulted in a 20% improvement, and the higher concentration of 2.5% resulted in a smaller improvement of 7.5%. These results confirm the great effectiveness of Nanofluids in improving the operation of gas turbines, which may contribute to enhancing cooling efficiency, reducing fuel consumption, and lowering operating costs, opening new horizons for the development of more efficient technologies in the energy sector.
