This work presents a post-data analysis procedure, namely, proper orthogonal decomposition (POD)–dynamic mode (DMD)–discrete Fourier transform analysis, for evaluating the dominant features of flow fields from both energetic and dynamic perspectives. The large-eddy simulation (LES) was first employed to reproduce field surrounding three types building layouts. Subsequently, POD DMD were conducted according LES results. extracted modes classified into based on DMD: Type-1 mode: energetically...
In this study, flow behaviors and vortex morphology around the sloping terrain that is covered by an atmospheric boundary layer are investigated using a combination of numerical experimental methods. An array wind tunnel experiments high-fidelity large eddies simulations have been conducted, considering different slope angles θ = 90°, 45°, 26.5°, 18.2°. Systematic analysis turbulence phenomena pertaining to field's topography-driven distortions accelerations was performed quantitatively via...
This study conducts large eddy simulations (LES) to investigate the aerodynamic interference effects and flow field characteristics of around square cylinders, taking into account inclination disturbed structure. The configurations structures involve tandem side-by-side arrangements with angles structure including +15°, 0°, −15°. identification involves examination multiple components, particularly time-averaged velocity streamlines, axial patterns, instantaneous spanwise vortices, wake...
