Milanovic Publishes Two Research Papers at the AIAA AVIATION Forum


Ivana Milanovic, professor of mechanical engineering, CETA, published two research papers with NASA GRC colleagues at the American Institute of Aeronautics and Astronautics (AIAA) AVIATION Forum last month in Atlanta, Georgia. AIAA AVIATION is a premier, forward-looking forum designed to showcase recent innovations and achievements in aviation, highlight new initiatives and plans, and address key issues that need to be resolved in order to define clear roadmaps for future progress.

The paper ‘Resonance and Tones in Dual-Stream Nozzles’ reports on a numerical investigation whose objective was predicting the appearance of tones and studying their sources. It was found that some of the tones traced to a coupling between Strouhal shedding from the struts, which held different pieces of the nozzle together, and various duct acoustic modes. A focus of the work was on exploring the nature of the duct modes. First, elements of the numerical procedure were studied for a 4-strut nozzle, validating the results with existing experimental data. The approach was then applied to a 3-strut geometry and four different excitation methods. The predicted tones and associated duct modes are analyzed in detail.

The paper ‘Experimental and Computational Study of Tones Occuring with a Coaxial Nozzle’ explored the source of audible tones occurring in a coaxial nozzle in a range of low Mach numbers experimentally and computationally. The hardware was comprised of an inner and an outer nozzle, without a center-body, and held together by a set of four struts.

Supported by the Transformational Tools Technology (TTT) and the Commercial Supersonic Technology (CST) Projects under NASA’s Advanced Air Vehicles Program, this has been a joint effort among members of the Inlets and Nozzles (LTN) and the Acoustic (LTV) Branches together with Professor Milanovic. Dr. Milanovic is grateful for the support of the University of Hartford Harrison Faculty Development Grant.

Acoustics Students Win Prestigious Architectural Acoustics Award




Dr. Eoin King and Dr. Bob Celmer present Paul Mangelsdorf and Jacob Ott with their medals at commencement.


National Medal for Merit in Architectural Acoustics

An unexpected announcement was made at the CETA commencement ceremony in May - Paul Mangelsdorf '18 and Jacob Ott '18 had won the 2018 Robert Bradford Newman Student Medals for Merit in Architectural Acoustics.

This highly selective national award, administered by the Acoustical Society of America, is named for Robert B. Newman of BBN (Bolt, Beranek & Newman, one of the original acoustical consulting firms). Students selected for the Newman Medal must have demonstrated excellence in this discipline and in the application of acoustical design principles in the course of their studies.

Mangelsdorf and Ott had participated in a research project studying the transparency of an architectural grille used in a new concert hall at Clayton College in Minnesota. The results of their investigation were presented at the Acoustical Society of America's national conference this spring.

Mangelsdorf graduate cum laude with a Bachelor of Science in Engineering, majoring in Acoustical Engineering & Music. Originally from Lagrangeville, New York. Mangelsdorf has accepted a position as an acoustic engineer with Thornburn Acoustical Consulting in Raleigh, North Carolina.

Ott graduated summa cum laude with a Bachelor of Science in Engineering, majoring in Acoustical Engineering & Music. Ott hails from Vernon, CT, and has accepted a position as an acoustic engineer with AKRF Acoustic Consultants in New York City.

Acoustics Students Win Prestigious Noise Control Award




Dr. Eoin King and Dr. Bob Celmer present Beranek Award to Jarrett Lagler and Alex Aquila, '18
 

Students at the University of Hartford have won a highly selective award called the Leo Beranek Student Medal for Excellence in the Study of Noise Control. The award was presented to the team of Jarrett Lagler '18 and Alex Aquila '18 during a surprise announcement at Commencement in May, at the diploma presentation ceremony for the College of Engineering, Technology, and Architecture (CETA).
 
The team of Lagler and Aquila were honored for their research work on "Using Ultrasonic Sound to Create Mid-Air Haptic Sensations". The award comes from the Institute of Noise Control Engineers and honors legendary acoustic engineer Leo Beranek.
Lagler (who also was awarded the Ribicoff Prize at the main graduation ceremony) graduated summa cum laude with a Bachelor of Science in Engineering, majoring in Acoustical Engineering and Music. Originally from Zionsville, Pennsylvania, Lagler has accepted a position as an acoustical engineer in the Audio Design Group at Apple, Inc., in Cupertino, California.
Aquila graduated summa cum laude with a Bachelor of Science in Mechanical Engineering with a Concentration in Acoustics. Originally from Ohio, Aquila has accepted a position as an acoustic engineer with Metropolitan Acoustics in Philadelphia, Pennsylvania.
