(2016-06-01)The Oran W. Nicks Low Speed Wind Tunnel (LSWT) uses a large-scale pyramidal-type balance to measure aerodynamic loads. The balance was built before computers were widely available and, consequently, it was designed to have ...
-
(2012-07-16)This dissertation investigates characteristics of the vertical distributions of mass flux observed in field and laboratory experiments. Thirty vertical mass flux profiles were measured during a field experiment in Jericoacoara, ...
-
(2013-04-19)This thesis describes the development and assessment of an undergraduate wind tunnel test engineering course utilizing the 7ft by 10ft Oran W. Nicks Low Speed Wind Tunnel (LSWT). Only 5 other universities in the United ...
-
(2013-01-15)Skin friction drag reduction is one of the most promising paths in the investigation of the reduction of aircraft fuel burn. 40 – 50% of overall drag comes from the surfaces of the wings and stabilizers. Natural laminar ...
-
(2012-07-16)This work develops a discontinuous Galerkin finite element discretization of non- linear hyperbolic conservation equations with efficient and robust high order stabilization built on an entropy-based artificial viscosity ...
-
(2017-12-06)Current and new FAA regulations that are to be phased in have begun to pressure the aerospace industry to develop new noise reduction technologies to reduce aeroacoustic emissions that proponents say detriment the health ...
-
(2010-07-14)Previous studies have demonstrated that EPA approved federal reference method (FRM) samplers can substantially misrepresent the fractions of particles being emitted from agricultural operations due to the relationship ...
-
(2017-10-17)Wind turbine blades are growing progressively larger and lighter relative to their size, and these trends can lead to early failure due to fatigue. Effort to design fatigue-resistant blades relies on understanding of ...
-
(2017-02-21)Air pollution, especially particulate matter (PM), is of growing concern in the United States and around the world. PM with aerodynamic diameter (AED) less than 2.5μm is currently one of the two indicators for PM pollutions. ...
-
(2020-03-26)The Air Force Office of Scientific Research Boundary Layer Transition (BOLT) flight experiment is a collaboration between academia, government, and industry. The objective was to challenge the hypersonic aerodynamics ...
-
(2015-01-22)Laminar flow has the potential to dramatically reduce fuel consumption and/or extend the range of modern aircraft. However, before laminar-flow aircraft can be made practical, the effect of surface imperfections must be ...
-
(2022-07-06)Improved modeling of hypersonic turbulent shear layers is of national interest. The Reynolds numbers experienced preclude widespread use of high fidelity simulations, and the complexity of the flow is not captured by simpler ...
