Surface dielectric barrier discharges (DBDs) are used to delay flow separation behind a bluff body in atmospheric pressure air. The bluff body is made by connecting a flat plate to a half cylinder tangentially as a round-cornered trailing edge. Four DBD plasma actuators are attached along the surface of the half cylinder. Particle Image Velocimetry (PIV) is utilized for studying the velocity fi...

Experimental studies dealing with the wake of isolated stationary bluff bodies are reviewed. After briefly recalling pioneering works in this domain, paper focuses on recent research conducted latest experimental methods and techniques. The review encompasses a range topics, including effects body geometry (non-circular cross sections non-uniformity spanwise direction), steady unsteady (periodi...

The present study in spin stabilised disc aerodynamics builds on previous experimental wind tunnel work to broaden the knowledge base through CFD simulation without the necessity for high facility or time cost. The current experimental database from previous studies is extensive enough for sufficient validation to be conducted on known geometries. From there, the limitations of CFD studies for ...

To develop reliable computer models for the bluff body flow and transport of pollutants or chemical and biological (CB) agents in urban environments requires accurate measurements of the basic flow fields for carefully controlled, well-known conditions. Fluid modeling in an Industrial Wind Tunnel provides an opportunity to produce accurate simulations of the bluff body flow and transport of urb...

Bluff-body flame instabilities are experimentally investigated under varying turbulence conditions during lean blowout. For all conditions, the blowout process is induced through a temporal reduction of fuel flow rate to capture flame-flow dynamics approaching Simultaneous high-speed particle image velocimetry (PIV), stereoscopic PIV, and C2*/CH* chemiluminescence imaging employed, along with a...

Truth-telling behavior in university students (n=38) was examined using a simple stylized poker experiment. Four treatments were applied that changed either card probabilities or payoff structure. Results indicated that in some cases the students’ behavior conformed closely to theoretical predictions. However, other cases indicated robust inconsistencies between observed behavior and mixed-stra...
