Design and CFD modeling of a solar micro gas turbine for rural zones in Sahel
This work presents a numerical design of a micro solar gas turbine for the rural areas of Sahel. Thermodynamic analysis, Mean Line Method, Ansys Blade Gen, Ansys CFX Turbo Grid and Ansys CFX solver were used to do the conceptual study and numerical analysis. The Mean line design results of solar micro gas turbine give a rotation speed of 115,000 rpm, a pressure ratio of 4, an expansion power equal to 40.28 kW and a compression power equal to 29.97 kW for an air flow of 0.14 kg.s−1 and a turbine inlet temperature equal to 850°C. Total to total turbine efficiency is 80% while compressor polytropic efficiency is 79%.
