New Trends in Multiscale and Multiphysics Simulation of Transport Phenomena in Novel Engineering Systems
The paper reports on the progress made in predicting large- and small-scale single and two-phase flows with heat transfer using the CMFD code TransAT. In the multi-phase context, the code uses the Level Set approach as the “Interface Tracking Method” of reference. The solver incorporates phase-cha...

description |
The paper reports on the progress made in predicting large- and small-scale single and two-phase flows with heat
transfer using the CMFD code TransAT. In the multi-phase context, the code uses the Level Set approach as the
“Interface Tracking Method” of reference. The solver incorporates phase-change capabilities, surface tension and
triple-line dynamics models, Marangoni effects, electric and magnetic fields, and a wall micro-film sub-grid scale
model for lubrication. Complex 3D examples shown here were treated using a fully automatized version of the code,
using the Immersed Surfaces Technique (IST) to map complex components into a simple rectangular Cartesian grid.
It is shown that real coupled two-phase heat transfer (conjugate) problems are within reach of modern CMFD code
using interface tracking, with relatively fast response times: 3D coupled two-phase flow heat transfer can run on a
simple Linux PC cluster within 24 H time. |
