Aerodynamically-generated sound is an important component of the unsteady motion of compressible fluids.  Tonal sound sustains feedback loops in airfoils, impinging jets and cavities while broadband sound is produced by turbulence.  The workshop will focus on predicting and controlling aerodynamically-generated sound in an increasingly complex series of example problems in one- and two-dimensions.  After introducing the essentials of sound generation and propagation, the numerical techniques required to simulate sound will be presented so that workshop attendees can implement and evaluate them.  Focus will then turn to sound control strategies, including adjoint and reduced order model-based approaches.  Numerical projects will reinforce the ideas presented as well as to enable better student proficiency with computational aeroacoustics.

Invited Keynote speaker:

Daniel J. Bodony is the Blue Waters Associate Professor and Donald Biggar Willett Faculty Scholar in the Department of Aerospace Engineering at the University of Illinois.  He received his Ph.D. in Aeronautics & Astronautics from Stanford University in 2005.  After working at the NASA Ames/Stanford Center for Turbulence Research he joined the University of Illinois in late 2006 as an assistant professor.  He received an NSF CAREER award in 2012 in fluid dynamics and is an associate fellow of the AIAA.


The workshop will take place at the picturesque estate of Montestigliano in the heart of Tuscany. The village of Montestigliano is composed of 18th century buildings, typically of Tuscan architecture. Located 15 km south-west of Siena, it provides a stunning landscape and a stimulating environment for both intensive work and relaxation. The 18th century houses and farm buildings have been carefully restored to retain their original features common to Tuscan architecture.

About ERCOFTAC Montestigliano Spring School

Ercoftac Montestigliano Spring School is an event for young scientists covering a specific multi-disciplinary and modern topic in fluid mechanics. Its format is based on an interactive teaching concept. Besides the traditional supervision by the student's advisor, the typical education of a PhD student seldom involves hands-on training under the guidance of a true expert in a particular and complementary field. University courses succeed in laying a foundation in rudimentary (and even a few specialized) concepts. Conferences, minisymposia and standard workshops expose young scientists to recent advances.In Montestigliano, students collaborate intensively during a full week in small groups under the guidance of a world-leading expert in a specialized topic.


The workshop starts with two or three (~2h long) lectures by the invited speaker on the chosen topic. During the week the students work in groups of 3-4. They are given a challenging project designed by the invited speaker and the organizers. The projects are often supplemented by Matlab codes and other material (papers, notes) that form an ideal starting point for the students. The projects are commonly divided into three categories: (A) basic concepts, (B) advanced concepts and (C) open questions at a research level. Students present their projects on the final day and submit a report 1-2 months after the workshop. In exceptional cases, these reports form the basis for a journal publication. The speaker and organizers are available during the entire week and work in close contact with the groups, helping out when difficulties arise or filling in missing knowledge.
Being in a remote area of Tuscany, the participants (organizers and student) are responsible for lunches and dinners. In this way, the student quickly become aquatinted with each other and a very warm and friendly atmosphere is created.

How to apply

Applications of prospective participants should contain:

1. A Curriculum Vitae (CV) or resume of the applicant (max one page
2. A short letter of purpose from the student (max one page), highlighting in particular the relevance of the workshop to his/her research topic.
A short description of the research topic should also be included.
3. A short letter of recommendation from the supervisor of the applicant (max one page).
This letter should be sent directly by the advisor to the organizers.
The applications can be submitted to any of the organizers.
Selected candidates will subsequently be notified and will receive a fellowship
that covers accommodation. Travel costs to and from the workshop venue have to carried by the home institute. Registration fee is 100€.

Deadline for applications: 31st January 2017
