Abstract

Abstract This paper presents an analysis of the unsteady heat release rate response of industrially relevant axisymmetric premixed flames to harmonic velocity perturbations. The heat release rate response, quantified using the Flame Transfer Function (FTF) definition, is measured from an acoustically forced swirl burner under perfectly premixed conditions. To understand the features of the measured FTF, a physics based analytical model is developed in this study. To describe the heat release rate dynamics, a model for the flame spatiotemporal response is derived in the linear limit using the G-equation formulation. Inputs to the flame response model are selected to be consistent with values observed in the corresponding industrial burner, based on experimental and numerical studies. The relative contributions of acoustic and convecting vortical disturbances on specific features of the FTF are explored in this study. The results highlight the importance of capturing the appropriate disturbance velocity field as an input to the flame response model for accurate FTF predictions.

工业预混燃烧器火焰传递函数建模

摘要本文分析了工业相关轴对称预混火焰对谐波速度扰动的非定常放热速率响应。热释放率响应，量化使用火焰传递函数(FTF)的定义，从一个声学强迫涡流燃烧器在完美预混条件下测量。为了理解测量的FTF的特征，本研究建立了一个基于物理的分析模型。为了描述热释放速率的动力学特性，利用g方程推导了火焰在线性极限下的时空响应模型。根据实验和数值研究，选择与相应工业燃烧器中观察到的值一致的火焰响应模型输入。本研究探讨了声波和对流涡旋扰动对FTF特定特征的相对贡献。结果强调了捕获适当的扰动速度场作为火焰响应模型的输入对于准确预测火焰火焰的重要性。
