Experimental wind tunnel study of airfoils with large flap deflections at low Reynolds numbers
Lift, drag, and moment measurements were taken at low Reynolds numbers for four airfoils with trailing edge plain flaps in an attempt to understand the effects of Reynolds number, percent thickness (t/c), percent chord of flap (flap-chord ratio), and flap deflection on airfoil performance. The four …

Wind tunnel study of wind farms with alternating 2- and 3-bladed wind turbines
With offshore wind farms gaining substantial momentum in recent years, 2-bladed turbines (2BT) are increasingly becoming a viable alternative to 3-bladed counterparts (3BT). In this wind tunnel study, model wind farms with alternating rows of 3BT and 2BT were explored for potential benefits …

Investigation of PM Formation and Evolution in Plumes Emitted by Heavy-Duty Diesel Vehicles: Wind Tunnel Study
… in the dilution process. In light of this, the study of the exhaust plume of a heavy-duty diesel vehicle operated inside a subsonic environmental wind tunnel can give us an idea of the dilution process and the representative emissions of the real-world scenario. The wind tunnel used for this …

Wind-induced dispersion of building exhaust in an urban environment : a full-scale and wind-tunnel study
… dispersion models. As another alternative, a wind tunnel study can be carried out to predict peak concentrations at critical locations. However, neither ASHRAE models nor wind tunnel modeling have been thoroughly validated with full-scale data. For the purpose of evaluating empirical formulas …

Experimental and numerical investigation of second-generation, controlled-diffusion, compressor blades in cascade.
… of the blades took place in a low-speed cascade wind tunnel using various experimental procedures. The objective of the wind tunnel study was to characterize the flow field in and around the blades at the off-design angle, and to investigate flow separation near the mid-chord for a high Reynolds …

Wind tunnel investigation of wind load on a ground mounted photovoltaic tracker
Wind loading is an important environmental factor to be considered in design of components and support structures of ground mounted photovoltaic tracker systems (PVT). Current understanding of action of wind on such systems is incomplete. Over the past decade, a number of investigations devoted to …

Effects of Aero-Propulsive Interactions for Various Wing Integration Techniques on Electric Ducted Fan Performance
This study explores the aero-propulsive coupling effects of wing blended electric ducted fans (EDF) lifting systems over the EDF unit. Wing blended EDFs and isolated EDF are on the rise as a solution to increase efficiency on regional mobility platforms. Electrification of platforms has permitted …

Characterization, modeling and mitigation of vortex-induced vibration of slender cylinders
… observed to vibrate at large amplitudes under wind excitation. Vortex-shedding was found to be one of the primary excitation mechanisms which manifests itself as distinct characteristics of the resultant problematic vibrations. The objectives of the proposed research are to formulate a …

Compound Aircraft Transport: Wingtip-Docked Flight Compared to Formation Flight
… for the hitchhiker and the system. The Stability Wind Tunnel (6 X 6 X 24 foot test section) at Virginia Tech, computational aerodynamic analysis with the vortex lattice method (VLM), and a desktop aircraft model were used to answer questions of the best location for a hitchhiker aircraft and …
