The Fuzzy C-means (FCM) method with Fourier coefficient-based distance was firstly used to construct the vortex features and analyze the large-scale unsteady flow pattern around the building by the transient ensemble velocity magnitude and Q criterion value. The performance of the unsteady Reynolds-averaged Navier-Stokes (URANS) turbulence models, including Standard (Formula presented.) model, Realizable (Formula presented.), Renormalization Group (RNG) theory (Formula presented.) and Shear-Stress Transport (SST) (Formula presented.) models on the flow structures around a high-rise building, w...

In a paper recently published in the journal Ocean Engineering, researchers employed a free-surface vortex method for crude oil recovery, while studying its flow process in a vortex by carrying out scaled laboratory experiments.
