Evaluation of Flow and Heat Transfer Inside Lean Pre-Mixed Combustor Systems Under Reacting Flow Conditions
Performer: Virginia Polytechnic Institute and State University
Project No: FE0011762
The goal of this project is to provide a better understanding of combustor swirling flow and its effect on liner surface heat transfer in order to improve prediction methods and design practices for cooling combustor liners in low emissions combustors. The project will focus on how the hot swirling gases interact with the liner wall of a gas turbine combustor. Results will provide insight into the effect of swirl nozzle exit flows and the mixing characteristics of fuel/air and its impingement on liner and dome regions. This will support the development of more effective cooling schemes to maintain and improve combustor durability.
