Abstract:In order to explore the drag reduction performance, an experimental and computational research effort for aero engine blade with micro-texture is undertaken. An optimized drag reduction model on blade with micro-textures is established for this effort in this paper. First, a new method is proposed to determine the placement position of micro-texture on blade surface through the analysis of flow domain around blade surface and geometric model of micro-textures on blade surface is established based on the proposed method. Then the section shape of micro texture with the better drag reduction performance is determined by FEA (Finite Element Analysis) simulation for the established geometric model of micro-textures on blade surface. Finally, an optimized method for drag reduction performance of micro texturing size is proposed and an optimized drag reduction model of textured blade is established. The simulation experiments for drag reduction performance of un-textured blade and textured blade with optimized micro-texture is conducted. The comparison results show that the established drag reduction model of textured blade has better drag reduction performance than that of un-textured blade and verify that the proposed methods to determine the placement position of micro-texture on blade surface and to optimize drag reduction performance of textured blade are satisfied.
