Stability analysis of a gas turbine exhaust stack
Stability analysis, based on finite element method, was carried out on a gas turbine exhaust stack following obvious appearances of significant gaps between its silencer casings and embracing rings. The finite element model was developed by referring to the corresponding technical drawing of the exh...
