Title of Document: SPRAY FLAME AND EXHAUST JET CHARACTERISTICS OF A PRESSURIZED SWIRL COMBUSTOR Martin Brendan Linck, Doctor of Philosophy, 2006 Directed By: Professor Ashwani K. Gupta Department of Mechanical Engineering This work describes an investigation of swirl-stabilized flames, created in a combustor featuring co-annular swirling airflows, under unenclosed, enclosed, and submerged condi...

An annular liquid sheet sheared by a coaxial supersonic gas stream with swirling effect is investigated using Large Eddy Simulation. Despite its wide applications in aerospace and medical devices, the instability spatial characters have been barely due to high complexity under condition. Unlike conventional use of temporal dynamic mode decomposition (DMD), DMD applied axial direction evaluate t...

Thermal performance of three different types of liquefied petroleum gas (LPG) domestic cooking burners, i.e. a conventional radial flow, a vertical flow and a swirling flow were analyzed by means of Particle Image Velocimetry (PIV). PI V diagnostics can explain the burners’ performance from their corresponding flow fields at an impingement area. With the difference of flow patterns, larger atta...
