A numerically robust, parallel-friendly variant of BiCGSTAB for the semi-implicit integration of the viscous term in Smoothed Particle Hydrodynamics

Autor: Bilotta, Giuseppe, Zago, Vito, Centorrino, Veronica, Dalrymple, Robert A., Hérault, Alexis, Del Negro, Ciro, Saikali, Elie

Implicit integration of the viscous term can significantly improve performance in computational fluid dynamics for highly viscous fluids such as lava. We show improvements over our previous proposal for semi-implicit viscous integration in Smoothed P

Numerical modelling of an air-helium buoyant jet in a two vented enclosure

Autor: Saikali, Elie

Nous cherchons à modéliser numériquement un jet flottant air-hélium dans une cavité avec deux ouvertures à partir de simulations aux grandes échelles (LES) et de simulations numériques directes (DNS). La configuration considérée est basée

A new open source CFD-scale multi-phase flow environment has been developed in the TrioCFD code using the TRUST HPC platform. Mass, momentum and energy equations can be solved for an arbitrary number of phases. This environment is scalable, can use m

Modélisation numérique d'un jet flottant air-hélium dans une cavité avec deux évents

Autor: Saikali, Elie

Publikováno v: Mécanique des fluides [physics.class-ph]. Sorbonne Université, 2018. Français. ⟨NNT : 2018SORUS023⟩

We present numerical results from large eddy simulations (LES) and coarse direct numerical simulations (DNS) of an air-helium buoyant jet rising in a two vented cavity. The geometrical configuration mimics the helium release experimental set-up studi
