Updraft novel6/1/2023 Solar energy is a highly viable option as it is free and abundant. Solar, wind, rain, tides, and geothermal energy are viable sources of renewable energy for generating electrical power. The results were compared with the existing experimental data and found promising agreement.įossil fuels create tremendous environmental harm, so renewable energy sources need to be encouraged for more carbon free energy generation. These abrupt variations in performance parameters proved that the fillet makes much impact on the SUT system and therefore it must be built on the base of the chimney. Also, case 2 produced a P the of 141 kW, η coll of 62% and η o of 0.25% which are with an enhancement of 73.3%, 48.44% and 72.4%, respectively. Higher updraft velocity (about 38.5% rise) was observed due to the provision of fillet in case 2. Comparative analysis was done between Case 1 and Case 2 on various performance characteristics such as turbine power ( P the), collector and overall efficiencies ( η coll, η o). Two models of the SUT plant were developed Case 1 having no fillet, Case 2 having a 45° square fillet. The real SUT plant (Manzanares, Spain) dimensions were considered for this three-dimensional analysis. The present work provides an in-depth numerical investigation and thereby enhancing the thermal performance of the SUT plant. However, a conventional SUT plant is not economical due to its lower thermal performance. Solar updraft tower (SUT) plant is one of the potential technologies for carbon-free power generation.
