Flow past sphere at high reynolds number
WebJan 18, 2024 · A numerical study of stably stratified flows past spheres at Reynolds numbers and is reported. In these flow regimes, a neutrally stratified laminar flow induces distinctly different near-wake features. WebA single number, called the Reynolds number, can be used to predict the onset of turbulent flow. For the flow past a smooth cylinder or sphere of diameter D or through a smooth tube with diameter D we have …
