Experimental Validation of Numerical Blade Flutter Prediction

摘要: Blade flutter of modern gas-turbine engines is one the main issues that engine designers have to face. The most used numerical method employed for prediction energy method. Although a lot papers are devoted analysis different blade wheels, this was rarely validated by experiments. Typical mesh size, time step, and various modeling approaches guarantee reliable not commonly known, whereas some examples show predictions obtained through nonvalidated codes can be inaccurate. In paper, we describe our implementation Analysis convergence sensitivity abstractions carefully investigated. Numerical results verified compressor full test data. It shown onset rather so presented in paper other researchers industrial blades.
