Journal ArticleDOI
Comparative investigation of strut cavity and wall cavity in supersonic flows
TL;DR: In this paper , a strut and a cavity were combined into a strut cavity and compared with the wall cavity for different Mach numbers and aspect ratios, using numerical simulations, and oscillations were found to decrease for high values.
Journal ArticleDOI
A review of aircraft subsonic and supersonic combustors
TL;DR: In this paper , a review of the combustion processes of subsonic and supersonic burning conditions is presented, such as ignition, flame propagation, and flame stability, and various flame holders are evaluated.

Fundamental Studies of Cavity-Based Flameholder Concepts for Supersonic Combustors
TL;DR: In this paper, the authors investigate the effect of the aft ramp angle on the character of the shear layer that spans the cavity in a nonreacting supersonic ship.

Turbulent Flow Past a Backward-Facing Step: A Critical Evaluation of Two-Equation Models
S. Thangam,Charles G. Speziale +1 more
TL;DR: In this paper, the ability of two-equation models to accurately predict separated flows is analyzed from a combined theoretical and computational standpoint, and it is found that the errors in the reported predictions of the k-epsilon model have two major origins: (1) numerical problems arising from inadequate resolution, and (2) inaccurate predictions for normal Reynolds stress differences arising from the use of an isotropic eddy viscosity.
