An arrangement to control vibrations in a gas turbine exhaust diffuser is provided. The arrangement includes a protrusion coupled to a turbine exhaust cylinder strut for controlling shock induced oscillations in a gas turbine diffuser. The controlled shock induced oscillations minimize pressure fluctuations in the gas turbine exhaust diffuser such that an unsteadiness of the fluid flow surrounding the turbine exhaust cylinder strut is reduced. A method to fluid flow induced vibrations in a gas turbine diffuser is also provided.
1. An arrangement to control vibrations in a gas turbine exhaust diffuser, comprising: a gas turbine exhaust diffuser, comprising: a turbine exhaust manifold connected to a turbine exhaust cylinder establishing a fluid flow path, the fluid flow path bounded radially outward by an outer conical surface and bounded radially inward by an inner conical surface;a turbine exhaust cylinder strut comprising a turbine exhaust cylinder strut airfoil arranged in the turbine exhaust cylinder between the outer conical surface and the inner conical surface; anda protr...
