Existence of Non-Isothermal two-phase flow solver in RheoTool Extension of OpenFoam

Fl7 · February 22, 2024, 10:24

Hi,

I am engaged in the challenging task of modelling a non-isothermal two-phase flow, specifically planar die swell, using the RheoTool extension of OpenFOAM for a non-Newtonian fluid.

While there is an existing solver, rheoInterFoam, tailored for isothermal modelling of non-newtonian two-phase flow, I have encountered a gap in finding a suitable solver for non-isothermal scenarios.

I'm reaching out to the community to inquire if anyone is aware of a solver within the RheoTool extension of OpenFOAM designed for non-isothermal two-phase flow modelling.

Any insights or recommendations in this regard would be immensely helpful.

In the absence of such a solver, I am studying two potential approaches: applying a Volume of Fluid (VOF) formulation to RheoHeatFoam or introducing a temperature field to rheoInterFoam.

If anyone have any experience or insights on these approaches, or if anyone could provide any recommendations or advice, I would greatly appreciate your input.

Thank you for your time and support.
Sam

Hello! I am also looking for solutions for the non-isothermal two-phase flow of non-Newtonian fluids， specifically for 3D printing applications. Have you found any relevant information? Could you help me? Thank you!
