A transitional flow regime is known to induce complex structures upon aerodynamic geometries such as airfoils, and the dynamics of laminar separation bubbles (LSBs) pose a relevant research field. In addition being affected by Reynolds value itself, LSBs are shown be equally sensitive surface roughness airfoils. The study analyses wind tunnel-derived surface-pressure distribution datasets obtai...

Numerical simulations of fluid flows can produce a huge amount data and inadvertently important flow structures be ignored, if thorough analysis is not performed. The identification these structures, mainly in transient situations, complex task, since such change time move along the domain. With decomposition entire set into smaller sets, present main with periodic behaviour, like vortices, ide...

This study examines the flow field dynamics of bluff-body stabilized swirling and non-swirling flames produced from Cambridge/Sandia Stratified Swirl Burner. burner has been used in previous studies as a benchmark for high-resolution scalar velocity measurements validating numerical models. The was designed to create reacting conditions that are representative turbulent flows modern combustion ...
