Following successful attempts to mimic flow controls employed by nature, innovative new flow controls were born. Owls have long been an exciting topic of research for reducing aerofoil noise. In this case, their feathers' porosity (the quality that allows air to pass resistively through the wings) helps in suppressing noise [6,7]. If this noise suppression could be harnessed without a detrimental effect to the aerodynamic performance of aerofoil, it would have significant industrial implications.Porous treatment on aerofoil is a promising research topic, but there are still many gaps in the current research which this PhD aims to fill:The Aerodynamic and Aero-acoustics PerformancesThe Adaptability of Porosity/PermeabilityPorosity at both the Leading and Trailing Edge of the aerofoil

在成功地尝试模仿自然所采用的流量控制之后，创新的新型流量控制诞生了。猫头鹰长期以来一直是减少机翼噪音的令人兴奋的研究课题。在这种情况下，它们羽毛的孔隙率（允许空气阻力地通过翅膀的质量）有助于抑制噪音 [6,7]。如果能够利用这种噪声抑制而不会对翼型的气动性能产生不利影响，那么它将具有重大的工业意义。翼型的多孔处理是一个有前途的研究课题，但本博士旨在填补的当前研究中仍然存在许多空白：空气动力学和气动声学性能孔隙率/渗透率的适应性翼型前缘和后缘的孔隙度
