| Summary: | Radial turbines are pivotal components in various engineering applications, playing a fundamental role in power generation, propulsion systems, and energy conversion processes. The efficiency and performance of these turbines are influenced by numerous design parameters, with the number of blades being a critical factor affecting overall efficiency. In this research, the effect of the number of blades is observed by using the numerical approach with CFD software. First, a turbine is designed, which refers to operational conditions. Next, the blade model is created by using blade design software. Then, three cases with 10,13 and 15 blades are conducted and simulated. The result shows that more blades give more power because more surface to extract the energy from the fluid.
