Numerical analysis of vertical axis gas turbine blade of different materials

Abstract

Turbine rotor blades are the key components of a gas turbine power plant. The turbine rotor blades are struck primarily by static loading conditions. This paper summarized the numerical analysis of the vertical axis gas turbine rotor blade components with different traditional and advance materials. CATIA V5 and ANSYS 11.0 are used for the design of model and optimization analysis for structural, thermal and modal of gas turbine rotor blade components. In optimisation analysis of the turbine rotor blade components, we used both ways of static and dynamic conditions for better understanding of the behavior of rotor blade materials. The rotor blade materials used for the optimization analysis was titanium, graphite and zirconium. The dimensions of the rotor blades used for the study were span length of 85 mm, chord length of 65 mm, thickness of 15 mm, cooling passage width of 3 mm in diameter and a total of 95 blades. The design analysis was conducted to examine the stresses, shear stresses, strains and displacements of the turbine rotor blades produced due to the external load impacts. The optimization was evaluated by contrasting the findings obtained from the result analysis of turbine rotor blade components made of graphite, titanium and zirconium alloys. The findings revealed that titanium alloy is a stronger substitute for use in gas turbine as a rotor blade element, relative to graphite and zirconium.
