The Onset of Turbulence in Pipe Flow Science
WebNov 29, 2024 · The phase transition to turbulence in spatially extended shear flows. Lukasz Klotz, Gregoire Lemoult, Kerstin Avila, Bjorn Hof. Directed percolation (DP) has recently emerged as a possible solution to the century old puzzle surrounding the transition to turbulence. Multiple model studies reported DP exponents, however experimental … WebJul 8, 2011 · One circumstance that complicates this problem is that laminar pipe flow is stable to infinitesimal perturbations (7, 8), and therefore in order to trigger turbulence, a disturbance of finite amplitude is required (1, 3, 9).What makes matters even more difficult is that at low Re, turbulence is transient.Here, turbulence occurs in the form of localized … WebAbstractPipe flow is a prominent example among the shear flows that undergo transition to turbulence without mediation by a linear instability of the laminar profile.Experiments on … how many people are intersex
