WebMay 22, 2024 · Churn flow, also referred to as froth flow is a highly disturbed flow of two-phase fluid flow. Increasing velocity of a slug flow causes that the structure of the flow becomes unstable. The churn flow is characterized by the presence of a very thick and unstable liquid film, with the liquid often oscillating up and down. Web对于Gradient Boost.

WebJul 31, 2024 · We discussed one very useful property of the gradient flow corresponding to the evolution of the Fokker-Planck equation, namely “displacement convexity”. This is a generalization of the classical notion of convexity, due to McCann, to the case of a dynamics on a metric space which asserts that there is convexity along geodesics.
