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...

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...

Determining when a numerical simulation is fully converged is important in getting accurate and reliable results. In this study a new convergence criterion based on extracting the energetic modes of a numerical solution, based on the Proper Orthogonal Decomposition method, is suggested. The POD convergence criterion is tested and applied to flow over a bluff body which has been solved numerical...
