Turbulence anisotropy in a bubbly vertical channel flow with topological change
Arturo A. Arosemena, Davide Procacci, Simone Di Giorgio +2
High-fidelity numerical simulations of bubble-laden, vertical channel flow in the upward configuration, where the bubbles undergo topological changes (breakup and coalescence), wer…
A universal diffuse interface modeling framework for surfactants
Shahab Mirjalili, Mathieu Bignolles
We propose a universal diffuse-interface modeling framework for surfactant transport in two-phase flows, applicable to all solubility scenarios and to any conservative phase field…
Solid adsorption: the missing mechanism for surfactant contact lines -- a phase-field approach
Parvathy K. Kannan, Kazi T. Iqbal, Diego DÃaz +5
We develop a thermodynamically consistent phase-field model for soluble surfactants in two-phase flows, incorporating both interfacial and solid surface adsorption. The model is de…
An LES model with finite-rate phase change and subgrid spray based on a thermodynamically consistent four-equation multiphase model
Henry Collis, Shahab Mirjalili, Makrand Khanwale +2
In this work, an LES model with finite-rate phase change and subgrid spray based on a high-resolution numerical scheme for multiphase multi-component simulations which satisfies in…
Convolutional autoencoders for the reconstruction of three-dimensional interfacial multiphase flows
Murray Cutforth, Shahab Mirjalili
We present a systematic investigation of convolutional autoencoders for the reduced-order representation of three-dimensional interfacial multiphase flows. Focusing on the reconstr…
A thermodynamically consistent and robust four-equation model for multi-phase multi-component compressible flows using ENO-type schemes including interface regularization
Henry Collis, Deniz A. Bezgin, Shahab Mirjalili +1
In this work, a concise and robust computational framework is proposed to simulate compressible multi-phase multi-component flows. To handle both shocks and material interfaces, a…
