TL;DR
This study compares how different materials used in wind turbine blades resist erosion, finding that material type and impact angle significantly affect erosion rates and performance.
Contribution
The paper introduces a multi-objective optimization approach combining erosion resistance and aerodynamic performance for wind turbine blade design.
Findings
Erosion rates increase with particle size and impact speed, but vary with impact angle depending on material type.
Optimal impact angles for erosion resistance and aerodynamic performance differ between metallic and non-metallic materials.
Multi-objective algorithms identified specific optimal angles for Kevlar, fiber glass, stainless steel, and aluminum alloy.
Abstract
Turbine blade erosion is a significant concern in the power generation industry, as it can reduce efficiency and increase maintenance costs. This study investigates the effect of impact speed, impact angle, and particle size on the erosion rate of turbine blades, using a combination of simulation models and experimental validation. Regression models were developed to analyze the influence of these factors on the erosion rates of both metallic and non-metallic turbine blade materials. The results indicate that erosion rates increase with particle size and impact speed, with impact angle playing a crucial role in the erosion behavior. For metallic alloys, erosion rates decrease with increasing impact angle, whereas, for non-metallic materials, the erosion rate increases proportionally with impact angle. To optimize erosion resistance and aerodynamic performance, three multi-objective…
