The goal of this Virginia Tech project is to provide a better understanding of the combustor swirling flow and its effect on liner surface heat transfer in order to improve prediction methods and design practices in combustor liner cooling for low emissions combustors. The project will focus on the interaction between the hot swirling gases and the liner wall within a gas turbine combustor. This will support the development of more effective cooling schemes to maintain and improve combustor durability.

Program Background and Project Benefits
This project will provide a better understanding of combustor swirling flow and its effect on combustor liner surface heat transfer. This will support the development of more effective cooling schemes to maintain and improve combustor durability, leading to reduced maintenance costs for turbine operators. Specifically, this project will focus on how the hot swirling gases interact with the liner wall of a gas turbine combustor to 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 and support the development of more effective cooling schemes.
