WebPresent work reports a comparison between laminar and turbulent bubbly-flow modules. The aim is to evaluate the differences between both modules, and if the adopted simplifications for laminar regime correctly describe the behavior of two-phase flow within the separator.

WebOct 4, 2024 · Currently I am trying to run the simulation for water-bubble (air) flow and have selected k-e bubble model. With this model I am asked to enter the size of the bubble and I am a bit confused if the size of the bubble I enter remains same or is it just the initial guess I provide to comsol which later changes during the simulation? WebFor users of the Mixer Module, COMSOL Multiphysics ® version 5.3a brings all turbulence models to rotating machinery, mixture models, and bubbly flow, as well as a revamped modeling workflow for rotating machinery interfaces with moving mesh.

WebMar 26, 2024 · The bubbly flow model is obviously used for gas bubbles in liquids. Since the momentum contribution from the dispersed phase is neglected, the model is only valid when the dispersed phase has a density that is several orders of magnitude smaller than the continuous phase.

The flow seems to work but I get very negative concentrations. initialy -10% but during the calculation in time this value drops to -50% of the inlet concentration. Is there a way to bind this concentration between the maximum (inlet) en 0? divinity 2 proving ground
