Reduced modeling of the NOx formation based on the reaction-diffusion manifolds method for counterflow diffusion flames

Chunkan Yu et al.

Summary: The accurate prediction of NOx formation is crucial for clean combustion. A reliable reduction technique for chemical kinetics is needed to accurately capture NOx formation in practical turbulent combustion processes while minimizing computational costs. This study focuses on using the hierarchical construction of Reaction-Diffusion Manifolds (REDIM) to include the NOx chemistry governed by slow chemical reactions. Two-dimensional (2D) and three-dimensional (3D) REDIM models are generated based on the hierarchical structure of the REDIM method. Sample calculations of NOx formation in methane/air non-premixed counterflow flames validate the effectiveness of the REDIM method for steady and transient processes.

Sensitivity of reaction-diffusion manifolds (REDIM) method with respect to the gradient estimate

Chunkan Yu et al.

Summary: In this study, a mathematical formulation for calculating the sensitivity of manifold-based simplified chemistry with respect to the scalar gradient was derived. The method provides insights into the importance of the scalar gradient in Reaction-Diffusion Manifolds (REDIM) chemistry and the sensitivity of the reduced scheme to the gradient estimate. The approach was validated using examples of simple reaction systems and real combustion systems. The developed sensitivity analysis can also be applied to other manifold-based methods.

A novel model for incorporation of differential diffusion effects in PDF simulations of non-premixed turbulent flames based on reaction-diffusion manifolds (REDIM)

Chunkan Yu et al.

Summary: In this work, the reaction-diffusion manifold (REDIM) reduced chemistry is used to simulate turbulent non-premixed flames. The consideration of reduced variable gradients as additional parameters is a novel approach that successfully captures the system's multi-directional gradient characteristics. By utilizing one-directional gradients to generate REDIM reduced chemistry, the model accurately describes the influence of turbulence on differential molecular diffusion without the need for additional modeling.
