... of CO and UHC. Additionally, the cooling influence of water and the reactive NH 3 from urea breakdown may further suppress flame temperatures and reduce NO x emissions. The stability of flame structures has been effectively analyzed using proper orthogonal decomposition (POD) applied to high...

...Junjie Geng; Haiying Qi; Jialu Li; Xingjian Wang This work proposes an accurate and efficient surrogate modeling method for predicting combustion field in a gas-turbine combustor. The method integrates proper orthogonal decomposition-based dimensional reduction, and Gaussian process regression...

... coupled with detailed chemical reaction mechanism. Proper orthogonal decomposition method is applied to analyze the flow field characteristics, and the instantaneous velocity field is decomposed into four parts, namely, the mean part, coherent part, transition part, and turbulent part, respectively...
