Benchmark experimental data for time-dependent flow and heat transfer from a flat plate and improved understanding of the effects of low amplitude perturbations on the fluid and thermal behaviour

Flow pulsations/oscillations are known to have a great effect on the flow field, turbulence and subsequently heat or mass transfer and can be considered as an active method of heat transfer augmentation. On the other hand, periodic pulsations naturally occur in many biological (eg. blood vessels) and engineering systems (reciprocating pumps, IC engines or pulse combustors). The thermal and fluid behaviour of oscillating flows and their enhancement potential appear to be a subject of controversy in the literature as some investigators report significant heat or mass transfer improvements and others no effect at all.

The fundamental experiments of pulsating flows in the context of MinNOx have generated a set of benchmark experimental data that enables the scientific and industrial community to validate and further improve current numerical methodologies for the prediction of complex, unsteady flows and improve understanding of such flows.

Similar data have been generated for swirling flows which are also particularly complex and of practical importance to many engineering applications.

It is expected that the fundamental experiments carried out for MinNOx will open up new research opportunities for further systematic studies on the effects of flow pulsations/oscillations and swirl on transport processes so that the two technologies can be further explored and applied in process engineering.
