Teaching
Dr. Lyrintzis believes that effective teaching is of paramount importance and has made conscious efforts to enhance his teaching abilities (e.g. attended the Boeing Fellowship program, the advanced College Teaching Workshop at Purdue University, and the Bush program for teaching excellence at the University of Minnesota.).
Contribution in Course & Curriculum Development
Dr. Lyrintzis has taught a variety of courses covering the areas of Fluid Mechanics, Aerodynamics, Aeroacoustics, Flight Mechanics and Flight Dynamics. He has developed and re-organized several courses.
New Courses (ERAU)
1) Rotorcraft Aerodynamics (AE 536, Graduateelective course). This course includes a comprehensive treatment of helicopter aerodynamics and elements of helicopter design and wind turbine aerodynamics.
2) Aerodynamics (AE 319, junior required course). This course combines incompressible and compressible Aerodynamics for Astodynamics students.
New Courses (Purdue University)
1) Aeroacoustics (AAE/ME 615 Graduate elective course). Since the 90s there has been an increased concern about aircraft noise. This course addresses the problem of aircraft noise in a timely and useful manner. The course includes an introduction to theory of aeroacoustics with applications in jet noise, rotorcraft noise sonic boom, and fan noise. It was developed with the help of Professor Mongeau of the School of Mechanical Engineering at Purdue University and it is cross-listed with Mechanical Engineering.
2) Intermediate Aerodynamics (AAE 514 Graduate/Senior elective course). This course is a continuation of AAE 511 (Introduction to Fluid Mechanics) and covers the general area of aerodynamics at a graduate level. Some of the topics are: Incompressible aerodynamics, compressible aerodynamics, and airfoil/wing design. This course fulfills a need of the graduate curriculum in the Aerodynamics area and it is now (spring 2006) offered though CEE.
Reorganized Courses (Purdue University)
1) Rotorcraft Aerodynamics (AAE 515, Graduate/Senior elective course). The course was restructured to include a comprehensive treatment of helicopter aerodynamics and elements of helicopter design. The course was renamed rotorcraft aerodynamics.
Experimentation in Teaching Methods and Techniques
Several active learning techniques are employed. Example problems and typical exam questions are assigned during class time and the students are allowed to work in teams. Several homework and computer projects also involve teamwork. Many students have had positive comments about the techniques Dr. Lyrintzis uses.

Research Description
1. Integral methods for CAA.Dr. Lyrintzis has pioneered the use of surface integral techniques in Computational Aeroacoustics (CAA). Dr. Lyrintzis introduced the term “Kirchhoff method” in 1986 and published its first successful application that extends near-field CFD results to the acoustic far-field. Dr. Lyrintzis has utilized surface integral acoustic methods for rotorcraft and jet noise predictions. The impact of this work is very high, as these surface integral methods have become the preferred way for extending near-field CFD results to the far-field, and are used almost universally in CAA.
2. LES for jet Aeroacoustics.A new high-order accurate Large Eddy Simulation (LES) CFD code was developed with Professor Blaisdell (Purdue University) for jet aeroacoustics computations. The use of the LES code was extended for realistic Reynolds numbers using petaflop computing. Results were obtained with calculations of one billion grid points and using up to 91,000 cores in 2012. The code was enhanced to include nozzle walls utilizing an approximate turbulent inflow boundary condition and a wall model. The code was used for an analysis (done for the first time using LES) of the noise reduction concept of beveling the nozzle exit plane. Recently, the solver was further developed to include a sharp Immersed Boundary Method (IBM), to allow simulations of more complex nozzle shapes, i.e. chevrons. This is a pioneering effort and there are only a few research LES codes capable of such calculations. The impact of this work is significant. As the LES code predicts realistically and accurately the noise reduction trends for beveling,chevrons, as well as fluidic injection and it has become a very powerful tool to evaluate jet noise reduction strategies.
3. Other.In 2000 Dr. Lyrintzis formed and led a partnership with Rolls-Royce Indianapolis, the University of Southampton (home of Rolls-Royce Center on Acoustics), and Purdue researchers to investigate jet noise reduction strategies for flows with mixers. Dr. Lyrintzis (with Professor Blaisdell) were also supported by NASA Houston to improve the CFD code OVERFLOW by adding a new turbulence model designed for wall-bounded high Reynolds number flows with separation. Finally, Dr. Lyrintzis has worked on airfoil optimization and traffic flow modeling. All these efforts have a significant impact and advanced the state-of-the-art of the problems attempted.
