Journal ArticleDOI
Experiments and modeling of cavitating flows in venturi : attached sheet cavitation
TL;DR: In this article, the two-phase flow structures of attached sheet cavitation in Venturi geometries were described and a double optical probe measurements were performed and special data processing methods were developed to estimate void ratio and velocity fields for cold water flows.
Journal ArticleDOI
Rare Event Algorithm Links Transitions in Turbulent Flows with Activated Nucleations.
TL;DR: In this article, the authors used adaptive multilevel splitting (AMS) to get a very large statistics of transition paths, the extremely rare transitions from one state of the system to another.
Journal ArticleDOI
Computing Transition Rates for the 1-D Stochastic Ginzburg–Landau–Allen–Cahn Equation for Finite-Amplitude Noise with a Rare Event Algorithm
TL;DR: In this paper, the authors compute and analyse the transition rates and duration of reactive trajectories of the stochastic 1-D Allen-Cahn equations for both the Freidlin-Wentzell regime (weak noise or temperature limit) and finite-amplitude white noise, as well as for small and large domains.
Journal ArticleDOI
Statistical behaviour of adaptive multilevel splitting algorithms in simple models
Joran Rolland,Eric Simonnet +1 more
TL;DR: This work investigates the convergence in law of the algorithm as a function of the timestep for several simple stochastic models and considers the average duration of reactive trajectories for which no theoretical predictions exist, and investigates a three-state Markov chain which reproduces this phenomenon.
Journal ArticleDOI
Ginzburg-Landau description of laminar-turbulent oblique band formation in transitional plane Couette flow
Joran Rolland,Paul Manneville +1 more
TL;DR: In this paper, a model for plane Couette flow with a continuous transition from wall-bounded flow to turbulent and laminar domains is presented. But the model is adapted to the long time, large aspect-ratio limit.
