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…
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…
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…
A mass-conserving contact line treatment for second-order conservative phase field methods based on the generalized Navier boundary condition
Reed L. Brown, Shahab Mirjalili, Makrand A. Khanwale +1
A mass-conserving contact line treatment for second-order conservative phase field methods is presented and applied to the conservative diffuse interface (CDI) model. The treatment…
Assessment of an energy-based surface tension model for simulation of two-phase flows using second-order phase field methods
Shahab Mirjalili, Makrand A Khanwale, Ali Mani
Second-order phase field models have emerged as an attractive option for capturing the advection of interfaces in two-phase flows. Prior to these, state-of-the-art models based on…
Consistent, energy-conserving momentum transport for simulations of two-phase flows using the phase field equations
Shahab Mirjalili, Ali Mani
Realistic two-phase flow problems of interest often involve high flows with high density ratios. Accurate and robust simulation of such problems requires special treatments. I…
High Fidelity Simulations of Micro-Bubble Shedding from Retracting Thin Gas Films in the Context of Liquid-Liquid Impact
Shahab Mirjalili, Wai Hong Ronald Chan, Ali Mani
Micro-bubbles are of significant interest due to the long-living signature they leave behind naval ships. In order to numerically model and predict these bubbles in naval applicati…
Comparison between the diffuse interface and volume of fluid methods for simulating two-phase flows
Shahab Mirjalili, Christopher Blake Ivey, Ali Mani
A wide variety of interface capturing methods have been introduced for simulating two-phase flows throughout the years. However, there is a noticeable dearth of literature focusing…
A conservative diffuse interface method for two-phase flows with provable boundedness properties
Shahab Mirjalili, Christopher B. Ivey, Ali Mani
Central finite difference schemes have long been avoided in the context of two-phase flows for the advection of the phase indicator function due to numerical overshoots and undersh…
