WebMar 1, 2024 · However, the performance of a turbine is dominated by the flow in it. The simulations of flow details in a Pelton turbine were conducted in the present work and a kind of negative flow that is two jets flow into the same bucket was detected and evaluated. It will affect the efficiency and the torque character of Pelton turbine. WebPelton turbine design. Flow inside Pelton turbine is most complex due to multiphase (mixture of air and water) and free surface in nature. Numerical calculation is useful to understand flow physics as well as effect of geometry on flow. The optimized design is obtained using in-house special optimization loop.
