Laminar flow over airfoil speakers
High lift airfoils High performance airfoils reliant on carefully controlled adverse pressure gradients thus show a rapid deterioration in performance outside a narrow envelope [12]. Therefore, the moment coefficient for any angle of attack at the quarter chord is zero by theory. Lift and drag also vary directly with the density of the air. The chord line is the straight line from the leading edge to the trailing edge of the airfoil.

The senior capstone project is one of the most intensive, memorable, and eye-opening experiences in the undergraduate program. May 28, at 4pm or watch the stream later on YouTube.
BSAAE students complete a rigorous design and build project focusing specifically on the skills and knowledge unique to the field of aerospace engineering. All projects provide students with focused industry mentoring, interdisciplinary teamwork, written and oral communication skills, engagement with regulatory requirements, fiscal and procurement management, social and ethical considerations, and market awareness.
The large team projects must accommodate both domestic and international students, so the selected topics must not involve any constraints related to export controlled material. When selecting a Capstone Project, students should weigh their research and subject interests, relevant skills to contribute, career goals and more. The UW College of Engineering COE Industry Sponsored Capstone Program is a college-wide effort that is designed to provide effective project-based and team-based education of undergraduate students to meet the needs of engineering, science and industry.
AeroVironment UAV This team will demonstrate the feasibility of deploying one or more quadcopter aircraft from the payload bay of an RC plane. The quadcopter will then recover from tumble and execute a mission to fly to a GPS located target where it will relay video footage back to a ground station.
Applewhite wants to streamline compatibility of their parts. Additionally, they are creating and implementing an interface for autonomous deployment of the Baton from an air vehicle. Boeing Disaster Response UAV This team will design an emergency response, high endurance UAV, carrying a payload that can provide cellular coverage to an operating area in addition to cameras.
Some of their requirements include a minimum of 12 hours endurance and a takeoff and land within feet. Their goal is to collect data to improve the current computational model of the circumgalactic medium. SARP Propulsion: Aerospike Nozzle This team will develop a subscale rocket engine utilizing an aerospike nozzle geometry with implementation of thrust vector control using fluid injection.

Alvaro Meseguer UPC 7. Colm-cille Caulfield University of Cambridge 5. The most well-known is the Kelvin-Helmholtz KH wavepacket, which arises from a linear instability mechanism of the flow and plays a key role in sound generation. Recently, other energetic coherent structures were shown to exist in the turbulent field, all associated with different regions of the frequency-wavenumber spectrum. At low frequencies and high azimuthal wavenumbers, streaks arise as a result of the lift-up effect, where elongated streamwise vortices or rolls generate streamwise elongated structures in axial velocity. At low frequencies and low azimuthal wavenumbers, structures are amplified via the Orr mechanism. Finally, at zero frequency and zero azimuthal wavenumber, a shock-cell structure may be generated by the pressure mismatch at the nozzle in imperfectly expanded supersonic jets, which can also be predicted using linear stability tools. The objective of this talk is to analyse the interaction between some of these structures with the KH mode, which may lead to insight on their effects on sound generation. To this end, a combination of reduced order models will be applied to both jets and confined shear layers, which will allow us to understand how the KH instability mechanism is modified by them. Most of his work is focused on the identification and analysis of the dynamics of coherent structures in turbulent flows, and he has been studying resonance phenomena and noise generation in shock containing jets since

Pardon my ignorance, I'm quite new to CFD, I'm modeling flow downstream of a moving surface a 3in diameter speaker. However after some number of speaker cycles, the flow sets up a small eddy and the solution diverges. I've tried reducing the mesh size and time step. If I run a trubulent case, the solution converges. Am I making a fundamental error?

Scott Lab E W. Guest Speaker: Dr. James Coder, University of Tennessee. Background: Dr. His current research focuses on computational aerodynamics with applications to ultra-efficient commercial aircraft, hypersonic vehicles, and rotorcraft, along with the development of reduced-order transition and turbulence models. Abstract: Laminar-turbulent transition is a critical phenomenon in aerodynamic flows and can have a leading-order impact on flight vehicle performance. In many cases of practical interest, prediction of transition from first principles can be prohibitively difficult due to high Reynolds numbers, geometric complexities, and inherent unsteadiness limiting the ability to perform direct numerical simulations or detailed stability analysis.

Tapan K Sengupta and ever since has been an active place of research from its inception in The emphasis of research is on developing high accuracy computing methods to aid in bridging the gap between theoretical and computational fluid dynamics and heat transfer.
Leonardo da Vinci made several sketches of the motion of fluid and made a number of observations about how water and air behave. Good at something; skilled; fluent; practiced, especially in relation to a task or skill. A fluent interface also called method chaining is a style of coding wherein commands return a pointer to the target object rather than returning void. Listary is ranked 2nd while Fluent Search is ranked 9th. Acrylic is a Fluent Design System component that adds physical texture material and depth to your app.
