Preface
ThefirstInternationalSymposiumonFlowInducedNoiseandVibrationIssuesand
Aspects (Flinovia) was held in Rome, Italy, in November 2013 at the Italian
Consiglio Nazionale delle Ricerche (CNR), and co-sponsored by CNR-INSEAN,
the University of Naples, and the Lyon Acoustics Centre (CELYA). Seventeen
presentationsweregivenbyauthorsfromEurope,theAmericas,andAsiaspanning
experimental and numerical methods for quantifying flow-induced forcing func-
tions, vibration response, and radiated sound. Most of the presentations were later
expandedintochaptersinthefirstbookofFlinoviaproceedings,alsopublishedby
Springer.
The second Flinovia was hosted at Penn State University in the USA on April
27–28,2017.TheFlinoviasymposiaaresponsoredevents,withnoregistrationfees
for participants. Flinovia II was co-sponsored by the Penn State Center for
Acoustics and Vibration (CAV), the Penn State Institute for CyberScience (ICS),
the International Institute for Noise Control Engineering (I-INCE), and the United
States Office of Naval Research (ONR).
The topics at the second Flinovia were broader, with 30 presentations spanning
twodays.HalfofthepresentationswerefromauthorsoutsidetheUSA,withpapers
from Australia,Belgium,Canada,France,Germany, Hong Kong,Italy,and Spain.
USA papers included five from Penn State, and ten from other universities and
companies, including Aerohydroplus, ESI, Florida Atlantic University, Illingworth
and Rodkin, Kansas University, Lehigh University, University of Michigan, Notre
Dame, and Virginia Tech.
Over 100 people attended the conference, representing academia, industry, and
government. Twenty-five percent of attendees were from outside the USA, 35%
were from industry and government, and 10% were from universities other than
Penn State.
The papers in this volume (23 of the 30 presented at the symposium) are sub-
dividedinto two main groups: (1) flow and (2) vibroacousticresponse. In theflow
group, papers are further subdivided into:

The vibroacoustic response group is subdivided into:
(cid:129) Numerical methods
(cid:129) Experiments
(cid:129) Innovative applications
However,severalpapersspanbothflowandvibroacoustics,aswellasnumerical
and experimental methods so the grouping is not exact. Several papers investigate
flow-induced forces, particularly those caused by turbulent boundary layer
(TBL) flow. Slow-moving flow over marine vehicles and automobiles along with
high-speed flow over aircraft is addressed. The flow-induced forces radiate sound
directly(see the‘SoundSources’papers)aswell asexcitestructuresintovibration
(see the ‘Vibroacoustic’ paper group). Numerical methods, like finite element
analysis, and experiments are used to assess structural vibration response to flow
excitation. Analytic and numerical methods, like boundary element analysis, are
used to simulate sound radiated by flow turbulence. In one case, fully coupled
fluid–structure interaction modeling is used to emulate human speech.
The second Flinoviawas highly successful, growing thenumber of authors and
participants from the first meeting in2013. Future meetings are being planned and
will maintain the features of the first two—two days of presentations with a small
number of invited papers (no parallel sessions). Participation by industry and
government will be strongly pursued to ensure transition of research. To monitor
future developments, please visit www.flinovia.org.
