Premixed hydrogen-air flames interacting with a hydrogen porous wall

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1561228

A laminar one-dimensional hydrogen-air flame travelling and quenching towards a chemically inert permeable wall (PW) is studied. Hydrogen flows through the wall into the premixed H2-air. The S3D numerical code with detailed chemistry is used. PW results are compared against results of an impermeable...

Experimental Investigation of a Bluff Body Burner for Distributed Hydrogen Injection

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1491018

A novel concept for injection of gaseous hydrogen (fuel) into a stream of air (oxidant) with in low-NOx gas turbine combustion systems is proposed and tested experimentally in a laboratory bluff body (BB) burner. Instead of conventional injection nozzles, that represent undesired point sources of th...

Computation of three-dimensional three-phase flow of carbon dioxide using a high-order WENO scheme

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1482424

We have developed a high-order numerical method for the 3D simulation of viscous and inviscid multiphase flow described by a homogeneous equilibrium model and a general equation of state. Here we focus on single-phase, two-phase (gas-liquid or gas-solid) and three-phase (gas-liquid-solid) flow of CO...

Identifying turbulent structures through topological segmentation

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1354044

A new method of extracting vortical structures from a turbulent flow is proposed whereby topological segmentation of an indicator function scalar field is used to identify the regions of influence of the individual vortices. This addresses a long-standing challenge in vector field topological analys...

Effect of fuel composition and differential diffusion on flame stabilization in reacting syngas jets in turbulent cross-flow

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1257012

Three-dimensional direct numerical simulation results of a transverse syngas fuel jet in turbulent cross-flow of air are analyzed to study the influence of varying volume fractions of CO relative to H<inf>2</inf> in the fuel composition on the near field flame stabilization. The mean fla...

Modeling of mean flame shape during premixed flame flashback in turbulent boundary layers

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1145298

Direct numerical simulations of freely-propagating premixed flames in the turbulent boundary layer of fully-developed turbulent channel flows are used for a priori validation of a new model that aims to describe the mean shape of the turbulent flame brush during flashback. Comparison with the DNS da...
