This study focused on the stabilization of lean premixed flames of n-butane/H 2/air with
swirl/bluff-body. The research explored four different hydrogen fractions (0, 20%, 40%, and …

The improved delayed detached eddy simulation method with shear stress transport model
was used to analyze the evolution of vortex structure, velocity and pressure fields of swirling …

This work investigates the combustion characteristics of CH 4-air/O 2 turbulent swirling
flames in a co-axial burner with radial fuel injection. The burner configuration consists of two …

In new generation aero-engines, lean-burn combustors are equipped with swirl injectors in
order to reduce pollutant emissions. At the exit of these combustors, the flow is dominated by …

In this paper, we investigate the capabilities of the unsteady Reynolds-averaged Navier–
Stokes (URANS) equations for capturing the helical structures found in a three-dimensional …

The vortex dynamics in a stratified environment is of fundamental importance in various flow
systems, however, the mechanism of successive vortex–interface interactions remains not …

In modern gas turbines, the High Pressure Turbine (HPT) is exposed to an extreme thermal
environment due to the burned gases leaving the combustor. The burned gases are …

In turbine disk cavity, rim seals are fitted between the stator and its adjacent rotor disk. A
coolant air injected through the turbine disk cavity to prevent the ingress of mainstream hot …

This paper reports an experimental and numerical investigation of a methane-air diffusion
flame stabilized over a swirler coaxial burner. The burner configuration consists of two tubes …

The precise prediction of the aerothermal conditions at the outlet of modern combustors of
aero engines is of primary interest in the aerothermal design of high‐pressure turbines. The …
