Evaluation Methodologies for Film Cooling Effectiveness in Combustion Chamber Flame Tube Sections

Abstract

Design of modern gas turbine power plants combustion chambers involves addressing inherently conflicting requirements, including reliability, operational efficiency, and reduced emissions. Advanced three-dimensional numerical simulation technologies offer the potential to partially supplant experimental testing while substantially enhancing its scope. However, the confident application of simulation-derived data in the design of complex engineering assemblies necessitates rigorous validation of the computational models employed. This study investigates film cooling mechanisms within the GTE flame tube through three-dimensional numerical simulations and contrasts the computational outcomes with conventional engineering methodologies.
