RISComputationally Efficient Workflow for Conjugate Heat Transfer With Large Eddy Simulation for Gas Turbine Combustors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Typical gas turbine combustor (GTC) and high-pressure turbine stage generally employs 10,000 to 100,000 small passages of cooling holes. Such an arrangement protects the solid walls through impingement and effusion cooling. ...
Large Eddy Simulation of Ammonia–Hydrogen Nonpremixed Flames Stabilized on a Bluff Body Burner
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The demand for carbon-free fuels such as ammonia (NH3) and hydrogen (H2) has been growing rapidly due to stricter environmental policies on carbon emissions. Since ammonia is easier to store and transport, it is considered ...
Evaluation of Combustion Models and Reaction Mechanisms to Predict NOx and CO Emissions From Densely Distributed Lean-Premixed Multinozzle CH4/H2/Air Flames
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. This work explores the importance of reaction mechanisms and combustion models on the flame length and emission characteristic prediction by computational fluid dynamics (CFD) simulations of a complex multinozzle ...
Solution-Based Mesh Adaption Criteria Development for Accelerating Flame Tracking Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Solution-based mesh adaption approaches have been widely studied and tested by different research groups to generate the required finer meshes in the critical regions on the fly while keeping the overall mesh count to a ...
