Investigation Of Performance And Cavitation Treatment In A Kaplan Hydro Turbine, Muhannad R. Al-Haddad May 2019

Investigation Of Performance And Cavitation Treatment In A Kaplan Hydro Turbine, Muhannad R. Al-Haddad

Theses and Dissertations

Cavitation is a phenomenon that occurs in various turbomachinery applications causing drawbacks on the. Some of these downsides are damaging the components of the system, generating noise and vibration, and loss of the turbine efficiency over time. Thus, it is imperative to address issue of cavitation to increase the life span of the equipment in addition to improve the system performance. This thesis introduces a method used to mitigate the cavitation phenomenon in a 3-inch Kaplan hydro turbine via injecting air at the leading edge of the rotor blades. The study is based on modeling the turbine using Computational Fluid …
