Abstract: Direct numerical simulation (DNS) with interface tracking of turbulent bubbly flows is becoming a major tool in advancing our knowledge in the area of multiphase modeling research. A comprehensive analysis of the turbulent ...

Abstract: Abstract. The implementation of the conservative level set method is presented for the open-source two-phase massively parallel finite-element based flow solver, parallel hierarchic adaptive stabilize transient analysis ...

Abstract: New criteria for fully resolving two-phase flow regime transitions using direct numerical simulation with the level set method for interface capturing are proposed. A series of flows chosen to capture small scale interface ...

Abstract: Abstract. Plasma discharges in bubbles and at gas–liquid interfaces are a promising route for water treatment and sustainable chemistry, where bubble size and shape strongly influence discharge behavior and the delivery ...

Abstract: An algorithm to prevent or delay bubble coalescence for the level set (LS) method is presented. This novel algorithm uses the LS method field to detect when bubbles are in close proximity, indicating a potential coalescence ...

Abstract: A contact angle control algorithm is developed and implemented in the multiphase interface tracking flow solver—phasta. The subgrid force model is introduced to control the evolving contact angle. The contact angle force ...

Abstract: High-fidelity flow boiling simulations are conducted in a vertical mini channel with offset strip fins (OSF) using R113 as a working fluid. Finite-element code PHASTA coupled with level set method for interface capturing ...
