Trailing Edge Serration & Leading Edge Undulation Aero-acoustic Noise Reduction Mechanisms Through 3-Dimensional Flow Structure Analysis

研究将集中在三个主要阶段。第一阶段(大约10个月)将集中于优化弧形前缘锯齿的气动声学和气动性能，这些锯齿的灵感来自于猫头鹰机翼上的那些锯齿(见图2)。这个以前从未在其他地方尝试过的新概念是在我最后一年的学士项目中提出的，到目前为止的结果表明，锯齿实际上可以被仔细优化，以实现机翼前缘降噪(图3)和升力生成性能(图4)的同步和显著改进。目前，我们正在准备为我在本科毕业论文项目中开发的这项受猫头鹰启发的尖端锯齿技术申请专利，该专利将得到RSDO的支持。我的博士建议是进行更深入的研究，以确定基本机制，并寻求开发基于相同的物理原理的前沿锯齿的控制策略。

The research will focus on three main stages. Stage 1 (approximately 10 months) will focus on the optimisation of aeroacoustic and aerodynamic performances of curved leading edge serrations that were inspired by those found on owl's wing (see Fig. 2). This new concept, which has never been attempted elsewhere before, was initiated in my final year Bachelor's project and the results so far have demonstrated that the serrations can in fact be carefully optimised to achieve simultaneous and significant improvements in aerofoil leading edge noise reductions (Fig. 3) and increased performance in lift generation (Fig. 4). Currently we are preparing to apply for a patent, to be supported by the RSDO, for this owl-inspired leading edge serration technology developed in my undergraduate dissertation project. My PhD proposal is to undertake more in-depth research to determine the fundamental mechanisms and seek to develop control strategies based on the same physical principles on the leading edge serration.
