The impact of film cooling on the heat release within a rotating detonation combustor

open access: yesApplications in Energy and Combustion Science
Rotating detonation combustors establish a detonation wave that continuously circulates inside a small annulus. The presence of the detonation wave and the downstream oblique shock within the small annulus coupled with high mass flow induces a high heat ...

Hybrid Oxygen Enrichment and Preheating Strategy for Performance Recovery in Ultra‐Lean Micro–Trapped Vortex Combustors

open access: yesEnergy Science &Engineering, Volume 14, Issue 6, Page 3028-3041, June 2026.
Ultra‐lean H2 micro‐combustor performance is boosted through regulated O2 enrichment and inlet preheating. A 16‐case Taguchi study (ϕ = 0.3) shows: controlled enrichment and heating increase radiative output and efficiency, but excessive O2/temperature causes flashback.

Thermomechanical Validation of an Additively Manufactured Test Chamber for Sustainable Aviation Fuel Atomization in Jet‐In‐Crossflow Conditions

open access: yesMacromolecular Symposia, Volume 415, Issue 3, June 2026.
ABSTRACT This study aims to validate the structural and thermomechanical reliability of an additively manufactured test chamber specifically designed for the experimental investigation of sustainable aviation fuel (SAF) atomization under jet‐in‐crossflow (JICF) conditions representative of gas turbine afterburners. The proposed test chamber is designed

Steady state design and thermal characteristics of a gas turbine blade with lateral holes using finite element analysis [PDF]

open access: yesMATEC Web of Conferences
Turbine blades are the separate components that make up the turbine section of a steam or gas turbine. The blades must transform the high-temperature, high-pressure gas that the combustor produces into energy.
