Comparison of Turbines Stability by Energy Characteristics |

| Abstract: | A turbulence equation has been derived from the alternated Euler's equation and been introduced into of a concept regarding optimum virtual operation condition. The turbulent patterns upstream and downstream of a runner were separated off and a comparison was made for the turbulent losses calculated by the energy characteristics of the turbine, in order to identify the risk under stable operation condition. |
