Dynamic Characteristics Analysis of an Oil Turbine

This work is to study the dynamic characteristics of an oil turbine (OT) in the lubricating system of large-scale steam turbines. The configuration and the functions of OT are introduced. The mathematical models are accordingly explored. In addition, the experiment results are predicted and compared with the theoretical prediction. Finally, the dynamic characteristics in the start-up procedure are simulated and analyzed. The agreement between the numerical results and the experiment observations is in general satisfactory. It shows that the numerical simulation approach is reliable, and could be applied into the dynamic characteristics research and optimization of other complicated fluid systems as hydropower station.
