Comparative Validation Study on Identification of Premixed Flame Transfer Function
, 2011 The flame transfer function (FTF) of a premixed swirl burner was identified from a time series generated with computational fluid dynamics simulations of compressible, turbulent, reacting flow at nonadiabatic conditions.

Atomic Tuning of Metal‐Support Interactions for Pathway‐Selective CO2 Photoreduction on TiO2
Advanced Science, EarlyView.Single‐atom Fe and Cu catalysts anchored on TiO2 steer photocatalytic CO2 reduction toward distinct pathways. Fe sites favor rapid *CO desorption and selective CO formation, whereas Cu sites stabilize *CHO intermediates, enabling deep reduction and C─C coupling. Combined spectroscopy and DFT calculations reveal how metal–support interactions and oxygen

Experimental Studies of Flame Transfer Function in Acoustically Excited Rijke Burners
, 2014 本研究實驗探討一聲波激擾之垂直管道，位於管道下方一預混層流火焰之火焰移轉函數。本實驗類似於Rijke管的配置方式，在管道中一端分別導入三個不同聲納之燃燒爐。火焰轉移函數係由火焰區上下游所量測之聲波強度來決定，它與火焰上下游的壓力及速度有關。正值得火焰轉移函數代表火焰可能產生自發性振盪。研究結果顯示火焰轉移函數與火焰所在位置之流聲導納有著很大的關聯。火焰在聲波場所在之位置決定火焰轉移函數之正負值，同時，也決定其大小，火焰當量比所扮演的角色，僅是決定火焰轉移函數之大小 ...

Modelling of premixed combustion in a gas turbine [PDF]
, 1998 Three steady state combustion models, two turbulence models and a model for tK'6 prediction of NO., were implemented and investigated on a simple backward facing step experiment as well as an experimental lean prevaporised premixed (LPP) combustor ...

Nonlinear analytical flame models with amplitude-dependent time-lag distributions [PDF]
, 2018 In the present work, we formulate a new method to represent a given Flame Describing Function by analytical expressions. The underlying idea is motivated by the observation that different types of perturbations in a burner travel with different speeds ...
