Visualization of Conventional and Combusting Subsonic Jet Instabilities

• Broschiertes Buch

Produktbeschreibung

Based on newinformation obtained on free microjets, this book explains the latest phenomenain flame evolution in the presence of a transverse acoustic field with roundand plane propane microjet combustion. It gives an overview of recentexperimental results on instability and dynamics of jets at low Reynoldsnumbers and provides the reader, step by step, with the milestones and recentadvances in jet flow stability and combustion. Readers will also discover aclarification of the differences between top-hat and parabolic round and planejet instability.

Chapters demonstrate features of the interaction between jet and crossflow, andhow experimental data testify to similarities of the perturbed flow patterns oflaminar and turbulent round jets. A similar response of the jets to externalacoustic oscillations is shown, as well as the peculiarities of the effect of atransverse acoustic field on downstream evolution of round and plane macro- andmicrojets. Basic features of round and plane, macro and micro jets' evolutionaffected by initial conditions at the nozzle outlet and by environmentalperturbations are highlighted.

Students of fluid mechanics will gain a solid foundation in hydrodynamicstability and combustion of subsonic jet flow and researchers will value thepresentation of special aspects of instability and transition. The work treatsboth theoretical and practical facets, and it includes supplementary materialsuch as PowerPoint multimedia notes based on results of laboratory scientificexperiments.
