Numerical analysis of hydrogen release, dispersion and combustion in a tunnel with fuel cell vehicles using all-speed CFD code GASFLOW-MPI

Autor: Yabing Li, Han Zhang, Mike Kuznetsov, Jianjun Xiao, W. Breitung, Jack Travis, Thomas Jordan

Publikováno v: International Journal of Hydrogen Energy

Hydrogen energy is expanding world-widely in recent years, while hydrogen safety issues have drawn considerable attention. It is widely accepted that accidental hydrogen release in an open-air environment will disperse quickly, hence not causing sign

Status of dynamic water film model development in 3-D CFD code GASFLOW-MPI for analysis of passive containment cooling system

Autor: Jack Travis, Maurizio Bottoni, Jianjun Xiao

Publikováno v: Annals of Nuclear Energy. 108:99-112

The advanced passive PWR AP-1000 and AP-1400 are pressurized water reactors (PWR) with advanced passive safety systems. Most recognize the passive containment cooling system (PCCS) as being one of the most important concepts for advanced passive safe

Development and Validation of the Parallel All-Speed CFD Code GASFLOW-MPI for Detonation of Premixed H2-Air Mixture in a Hemispherical Balloon

Autor: W. Breitung, Jack Travis, Jianjun Xiao, Mike Kuznetsov, Reinhard Redlinger

Publikováno v: Volume 8: Computational Fluid Dynamics (CFD) and Coupled Codes; Nuclear Education, Public Acceptance and Related Issues.

The objective was to develop a validated computational fluid dynamics (CFD) based approach for predicting hydrogen detonations and the mechanical loads. Applications of interest were scenarios relevant to hydrogen explosion risk assessment in nuclear

Real-gas Equations-of-State for the GASFLOW CFD code

Autor: Zhanjie Xu, Jinsheng Xiao, Jack Travis, D. Piccioni Koch

Publikováno v: International Journal of Hydrogen Energy. 38:8132-8140

GASFLOW is a finite-volume computer code that solves the time-dependent, two-phase homogeneous equilibrium model, compressible Navier–Stokes equations for multiple gas species with turbulence. The fluid-dynamics algorithm is coupled with conjugate
