Bubbles in Turbulent Flows: Data-driven, kinematic models with memory terms
Zhong Yi Wan, Petr Karnakov, Petros Koumoutsakos +1
We present data driven kinematic models for the motion of bubbles in high-Re turbulent fluid flows based on recurrent neural networks with long-short term memory enhancements. The…
A hybrid particle volume-of-fluid method for curvature estimation in multiphase flows
Petr Karnakov, Sergey Litvinov, Petros Koumoutsakos
We present a particle method for estimating the curvature of interfaces in volume-of-fluid simulations of multiphase flows. The method is well suited for under-resolved interfaces,…
A Computational Study of the Collapse of a Cloud with 12500 Gas Bubbles in a Liquid
Ursula Rasthofer, Fabian Wermelinger, Petr Karnakov +2
We investigate the process of cloud cavitation collapse through large-scale simulation of a cloud composed of 12500 gas bubbles. A finite volume scheme is used on a structured Cart…
