Investigation of a combustion driven oscillation in a refinery flare. Part A: Full scale assessment (2006)

Nathan, Graham Jerrold, Mullinger, Peter, Bridger, D., Martin, B.

An assessment of the cause of an intermittent combustion-driven oscillation in a full-scale refinery flare is reported. When present, ambient sound pressure levels in excess of 100 dBA are generated....

Impacts of a jet's exit flow pattern on mixing and combustion performance (2006)

Nathan, Graham Jerrold, Mi, J., Alwahabi, Zeyad, Newbold, G. J. R., Nobes, D. S.

The influence of modifying a jet's exit flow pattern on both the near and far-field turbulent mixing processes and on the resulting combustion performance, is explored. This reveals that, in...

The influence of inlet flow condition on the frequency of self-excited jet precession (2006)

Mi, J., Nathan, Graham Jerrold, Wong, C. Y.

A precessing jet flow can be generated naturally by a fluidic nozzle comprising a cylindrical nozzle-chamber with a large sudden expansion at its inlet and a small lip at its outlet. Such a...

The influence of geometric nozzle profile on the global properties of a turbulent diffusion flame (2006)

Langman, A. S., Nathan, Graham Jerrold, Mi, J., Ashman, Peter John

A detailed comparison of the global performance characteristics of flames issuing from a long pipe and smooth contraction nozzle is presented for the first time. The measurements reveal consistently...
