This thesis develops, validates and implements a multidomain spectral method for direct
numerical simulation (DNS) of turbulent compressible (carrier) flows laden with a dispersed …

Experiments conducted in helium axisymmetric jets with an annular coflowing air stream
yield critical values of the velocity ratio U 2∕ U 1 needed to suppress global instability …

The present work describes the application of countercurrent shear flow control to the
nonreacting flow in a novel step combustor. The countercurrent shear control employs a …

Efficient atomization of viscous liquids has widespread applications in industry. Numerous
research articles have focused on trying to make the atomization process more efficient and …

Countercurrent shear flow control has been shown as an effective method of increasing
volumetric heat release within a dump combustor due to an increase in turbulence …

Research to advance our understanding of countercurrent shear flow has been conducted
with particular emphasis on those characteristics of the flow that are beneficial in combustion …

Reacting flow studies in a novel dump combustor facility focused on increasing volumetric
heat release rates, under stable burning conditions, and understanding the physical …

Combustion control is examined in a backward-facing dump combustor burning premixed
and prevaporized JP10 at overall equivalence ratios between 0.6 and 0.8. Control is …

In this article we report a numerical investigation of reacting flow in dump combustors with
counterflow and modified step geometry. The flow is simulated by solving Reynolds …

The high velocity flow in a ramjet requires a flame stabilization scheme to prevent blowout.
Normally, this was done using a rapid cross-sectional area change like a backward facing …
