... notable discrepancies prior to the vortex street development, which is likely due to how each code simulated the approach to the vortex street in earlier time-steps. Acronyms AMG = algebraic multigrid preconditioner CFD = computational fluid dynamics CONTAIN = containment...

... and voiding phases as well as cladding dry-out onset. A simulation performed by a computational fluid dynamics (CFD) approach (NEPTUNE_CFD code) taking into account liquid–vapor interfaces by an interface-tracking method is also shown and compared with the others approaches. Conclusions on each code...

... and two-phase CO 2 flow. This paper presents a methodology for the computational fluid dynamic (CFD) simulation of sCO 2 flowing through a restriction under a wide range of flow conditions. Under an accidental situation, such as a pipe break, the inventory of sCO 2 leaks out through a small restriction...

.... Standard neutronics codes DRAGON and DONJON have been coupled with a new thermalhydraulics code developed based on the latest empirical heat-transfer correlation, which allowed for more accurate estimation of basic characteristics of a PCh SCWR. In addition, the computational fluid dynamics (CFD) Fluent...

..., and turbulent flows are investigated with the use of computational fluid dynamic (CFD) software, CD-adapco STARCCM+. The model is validated against theory for developing laminar flow in the benchmark study with excellent agreement. The model is also benchmarked for transitional and turbulent flows by Hausen...
