Study of entropy generation of hydrogen-air premix combustion of 1-D laminar planar and 3-D turbulent v-shaped flame channel flow configuration using (S3D) direct numerical simulation

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+938573

In this paper, 3D turbulent V-shaped flame channel configuration of H2 - air premix combustion is investigated for the examining transient entropy generation at atmospheric pressure. The analysis is based on computing the exact source terms of entropy transport equation using Direct Numerical Simula...

A Numerical investigation of a lifted H2/N2 turbulent jet flame in a vitiated coflow

http://www.sintef.no/en/publications/publication/?pubid=SINTEF+S5991

Numerical calculations of a lifted H2/N2 turbulent jet flame in a vitiated coflow of hot gases are presented. The calculations are performed using Magnussen's Eddy Dissipation Concept (EDC) for turbulent combustion, and are an extension to previously reported EDC modeling results presented by Cabra ...

Prediction of two-phase pipe flows using simple closure relations in a 2D two-fluid model

http://www.sintef.no/en/publications/publication/?pubid=SINTEF+S10389

This paper presents a comparison of pressure drop and liquid hold-up as calculated using different modelling strategies; a two-dimensional two-fluid model, a one-dimensional simulator, and engineering correlations. The numerical results are compared with experimental data. Interestingly, the two-di...

Computational Modeling of Nitric Oxide Formation in Biomass Combustion

http://www.sintef.no/en/publications/publication/?pubid=SINTEF+S5916

Nitric-oxide formation from fuel-bound nitrogen in turbulent non-premixed flames was investigated. The calculations were performed using the k-epsilon model for turbulence and the Eddy Dissipation Concept for turbulent combustion in conjunction with detailed chemistry of the chemical reaction mechan...
