2020年12月1日 · In this paper, an improved multi-scale two-phase solver is developed to simulate bubbly flow problems, in which the macro-scale bubbles are captured by VOF method and …

In this study, a new model was proposed that classifies the dispersed gas bubble phase into multiple bubble size classes based on bubble diameter and calculate individual velocity and …

2021年10月15日 · When the bubbly flow contains more than one bubble, the interaction between different bubbles may lead to larger bubble deformation and more complex evolution of …

Bubbly multiphase flows play a critical role in many industrial processes, including the production of synthetic fuel, as well as in determining the transfer of gases between the atmosphere and …

2019年7月24日 · MFC is an open-source tool for solving multi-component, multi-phase, and bubbly compressible flows. It is capable of efficiently solving a wide range of flows, including …

Many two-phase flow problems present obvious multi-scale characteristics due to the existence of bubbles, droplets and large interface. Typical multi-scale two phase flow problems include …

Multiphase flow is a profound problem of interest to a wide range of engineering, geophysical, and environmental applications. For example, in the fields of medicine and pharmacology, the …

To resolve this issue, we introduce the Multi-Phase Field (MPF) method, which mitigates bubble coalescence by applying an independent fluid fraction function to each bubble. Figure 1 shows …

Two main models have been developed to predict the complex fluid dynamics phenomena of a dispersed bubbly flow, namely, the Eulerian–Lagrangian and Eulerian–Eulerian frameworks. …

2020年10月21日 · Mass, momentum, and energy transfer in bubbly flows strongly depends on the bubble’s size distribution, which determines the contact area between the interacting phases. …
