Numerical Simulation of the Deflagration-to-Detonation Transition in Inhomogeneous Mixtures
TL;DR: In this paper, the hazardous potential of flammable hydrogen-air mixtures with vertical concentration gradients is investigated numerically, based on the formulation of a reaction progress variable and accounts for both deflagrative flame propagation and autoignition.
Journal ArticleDOI
Validation of a FLUENT CFD model for hydrogen distribution in a containment
TL;DR: In this paper, the authors applied CFD codes to predict the hydrogen distribution in the containment within the course of a hypothetical severe accident and get an estimate of the local hydrogen concentration in the various zones of the containment.

A review on hydrogen generation, explosion, and mitigation during severe accidents in light water nuclear reactors
TL;DR: In this paper, the authors provided a review of what has been done in the literature with regard to hydrogen generation in severe accidents of nuclear power plants and identified the literature gaps and underlined the need of developing a systematic hydrogen management strategy.
Journal ArticleDOI
Hydrogen Distribution in Nuclear Reactor Containment During Accidents and Associated Heat and Mass Transfer Issues—A Review
TL;DR: In this article, a review summarizes the experimental and numerical studies on hydrogen distribution and suggests opportunities for further studies and concludes that the distribution of hydrogen within the containment has important bearing on possibility, mode, and consequence of combustion in the containment.

The numerical computation of turbulent flows
Brian Launder,D. B. Spalding +1 more
TL;DR: In this paper, the authors present a review of the applicability and applicability of numerical predictions of turbulent flow, and advocate that computational economy, range of applicability, and physical realism are best served by turbulence models in which the magnitudes of two turbulence quantities, the turbulence kinetic energy k and its dissipation rate ϵ, are calculated from transport equations solved simultaneously with those governing the mean flow behaviour.

The prediction of laminarization with a two-equation model of turbulence
W.P. Jones,Brian Launder +1 more
TL;DR: In this article, the local turbulent viscosity is determined from the solution of transport equations for the turbulence kinetic energy and the energy dissipation rate, and the predicted hydrodynamic and heat-transfer development of the boundary layers is in close agreement with the measured behaviour.

COMPARISON OF DIFFERENT k-ε MODELS FOR INDOOR AIR FLOW COMPUTATIONS
TL;DR: In this paper, Jive k-e, two-equation models are evaluated for their performance in predicting natural convection, forced convection and mixed convection in rooms, as well as an impinging jet flow.
