Numerical Simulation of Differential Molecular Diffusion Effects in a Hydrogen-rich Turbulent Jet Using LEM3D

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1151051

The LEM3D stochastic model for numerical simulation of turbulent mixing is used to simulate differential molecular diffusion effects in an isothermal jet of hydrogen and Freon 22 issued into air. The computations are compared with a published experimental study of the flow configuration. Salient fea...

Stochastic simulation of scalar mixing capturing unsteadiness and small-scale structure based on mean-flow properties

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+970872

A key limitation of Reynolds-Average Navier-Stokes (RANS) simulation of mixing and reaction in turbulent flows is the lack of resolution of small-scale structure and associated unsteadiness. Various subgrid models formulated in state space have been developed to complement the RANS solution in this ...

Nonlinear simulations of combustion instabilities with a quasi-1D Navier–Stokes code

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+912187

As lean premixed combustion systems are more susceptible to combustion instabilities than non-premixed systems, there is an increasing demand for improved numerical design tools that can predict the occurrence of combustion instabilities with high accuracy. The inherent nonlinearities in combustion ...

Modelling thermo-acoustic instabilities in an oxy-fuel premixed burner

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1272360

The inherent non-linearities in combustion instabilities can be of crucial importance, and we here propose an approach in which the one-dimensional Navier-Stokes and scalar transport equations are solved for geometries of variable cross-section. The focus is on attached flames, and for this purpose ...
