F Sınıfı Gaz Türbini Kompresor Kanadının Yapısal ve Termal Analizinin Yapılması

Bu çalışmada gaz türbinlerinde kullanılan geometrisi belli son kademe kompresör rotor kanadının yapısal ve termal analizi ANSYS sonlu elemanlar programı kullanılarak yapılmıştır. Bunun için halihazırda mevcut olan kompresör kanadının 3 boyutlu modellemesi yapılmıştır. Daha sonra bu model ANSYS programına aktarılarak yapısal ve termal analizleri yapılmıştır. Yapılan analizlerde kanat geometrisinde oluşan parametreler saptanmıştır. Seçilen parametreler ile bir tasarım geometrisi oluşturularak mevcut kanadın çalışma koşullarındaki dayanımı incelenmiştir. Bu çalışmada konu edilen tüm dış parametreler gerçek saha şartlarında çalışan bir F sınıfı gaz türbininin değerlerinden alınmıştır. Alınan değerlerin kanat üzerinde farklı bölgelerdeki gerilmeleri incelenmiştir. Yapılan bu çalışma aynı zamanda tersinir bir mühendislik çalışması olup gerçek saha şartlarının kompresör kanatları üzerindeki etkileri analiz edilmiştir.

Structural and Thermal Analysis of F Class Gas Turbine Compressor Blade

In this study, the structural and thermal analysis of the final stage compressor rotor blades, which are currently used on-site, is performed by using the ANSYS program. For that reason, a 3D model of the existing compressor blade has been done. Later on, this model was transferred to the ANSYS program and analyzed. In the analysis, the parameters formed in the blade geometry were determined. By creating a design geometry with the selected parameters, the stress of the existing blade under operating conditions was examined. All external parameters in this study were taken from an F-class gas turbine operating under real field conditions. The stresses of the obtained values in different regions on the blade were examined. This study is also a reverse engineering study and the effects of real field conditions on the compressor blades have been analyzed.
