Aerodynamics of a Single Annular Combustor

A Technical Deep Dive: Analyzing the Aerodynamics of a Gas Turbine Combustor Sector

Introduction: The Critical Role of Aerodynamics in Combustor Design

This analysis details the experimental investigation of aerodynamics within a realistic Single Annular Combustor (SAC) sector, also known as a Fuel Rich Dome Combustor. In the design and development of Gas Turbine Combustors (GTC), aerodynamics are of the first priority, playing a vital role in combustion stability, emissions, and overall dynamics.

This article will focus specifically on the experimental methodology used and the key numerical findings from the study, which are based on Laser Doppler Velocimetry (LDV) and Particle Image Velocimetry (PIV) measurements.
