Experimental and Theoretical Study on Spray Angles of Bi-Swirl Coaxial Injectors
Journal of Applied Fluid Mechanics, 2018 An experimental and theoretical study was undertaken to investigate the effects of the recess length, swirl direction, and mixture ratio on the spray angles of the bi-swirl coaxial injectors with the inner, closed-type and outer, open-type swirl ...

Swirl Generation and Recirculation Using Radial Swirl Vanes [PDF]
Volume 3A: General, 1993 The concept of the Swirl Number and its effect on recirculation is reviewed and problems with it are identified. Swirl generation through the use of radial inlet swirl vanes is then studied. The effect of vane and swirl cup design on recirculation is then evaluated using finite element computer modeling and verified using tufting tests.

Prediction of the flow inside a micro gas turbine combustor [PDF]
, 2008 The main purpose of this study is to predict the flow dynamics inside a micro gas turbine combustor model. The flow field inside the combustor is controlled by the liner shape and size, wall side holes shape, size and arrangement (primary, secondary and

Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma
Advanced Engineering Materials, EarlyView.The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...

Simulation of the Internal Flow of the High-Pressure Swirl Injector
Journal of Thermal Science and Technology, 2009 The simulation of the internal flow of a kind of high-pressure swirl injector was carried out with multiphase and cavitation models basing on the movement mesh. The spray was also simulated with the result of the internal flow simulation.

Effect of Oxygen Content on Surface and Subsurface Integrity During Turning of Ti–6Al–4V
Advanced Engineering Materials, EarlyView.This study examines how oxygen content in the ambient atmosphere affects the surface and subsurface properties of Ti–6Al–4V during turning. Results show that oxygen does not influence surface roughness. However, machining in an extremely high vacuum‐adequate atmosphere increases surface hardness by up to 7.8% and induces compressive residual stresses ...
