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: v vi Preface (cid:129) Forcing functions (cid:129) Sound sources (cid:129) Experiments (cid:129) Numerical methods 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. State College, USA Stephen A.
