Aeroacoustics: Noise Reduction Strategies for Mechanical Systems

Learn how to reliably evaluate noise in a variety of mechanical systems and develop basic noise reduction strategies to improve their aerodynamic design and performance. Finding the right balance between achieving maximum aerodynamic performance and lowering the noise output to comply with regulations and ensure people's comfort and health is a complicated task. Many companies are nowadays asking for combined aeroacoustic and aerodynamic knowledge and for many engineers it can be difficult to translate complex aeroacoustic theories into practical design applications.

In this course you will acquire the knowledge and tools required in this challenging field, including aerodynamic design guidelines to maintain or improve machine performance. You will review fundamental aeroacoustic principles and propagation theories in order to estimate the sound generated by a variety of mechanical systems. You will also explore dedicated noise-reduction strategies to understand how to improve the aeroacoustics of potential design solutions. Apply this knowledge to your own work After learning the fundamentals of aeroacoustic sources of noise, you will apply the knowledge gained to practical, industry‑relevant exercises.

During the course you will learn how to change the aerodynamic performance of one mechanical system of your choice (an aircraft propeller, a wind turbine, a wing with flap and/or a jet in proximity of a wing) to obtain a quieter device. This course includes special lectures and material by leading companies, including Siemens/Gamesa, GRAS Microphones and National Instruments. You will also gain access to online tools and resources to tailor your formulations to your own test‑cases, and you will receive personalized advice and feedback from international experts in the field of aeroacoustics.

• Analyze fundamental noise source mechanisms and their origin.
• Analyze and evaluate the sources of noise in different mechanical systems.
• Design a strategy to work within noise regulations without compromising aerodynamic performance.
• Identify the most important aerodynamic parameters that affect the noise generation (e.g. performance of the system and operating regimes).
• Evaluate the optimum design and recommend improvements on the original one.

This course is primarily geared towards working professionals. Prerequisites: Knowledge of fundamental aerodynamics and calculus is an asset to the course. However, the course will fill in any gaps of knowledge in physics.

5 Weeks, 5 - 7 Hours per week

The two-level mutual trust-based quality assurance scheme has been adopted:

• at the university level: Technische Universiteit Delft has applied its internal quality assurance procedures and structures to the proposal of Aeroacoustics: Noise Reduction Strategies for Mechanical Systems it submitted to ENHANCE and to its implementation - the related learning activities,
• at the Alliance level: the body composed of Education Officers has made decisions regarding the inclusion of Aeroacoustics: Noise Reduction Strategies for Mechanical Systems proposed by Technische Universiteit Delft to the Innovative Learning Campus part of the joint ENHANCE educational offer, based on the compliance with the formal requirements and ENHANCE goals.
