Conditional Sampling Measurement to Identify Flame Structures in Turbulent Combustion
난류 화염 구조 규명을 위한 조건 평균 측정법
Abstract
Conditional sampling measurement is required for conditional averages as well as unconditional Favre averages to resolve different flame structures of turbulent combustion. A Favre average can be obtained as an integral of conditional average and Favre PDF in terms of the mixture fraction, which is a preferred choice as a sampling variable in diffusion controlled turbulent combustion. MILD combustion data are presented as an example for a conditionally averaged data set and comparison with CMC calculation results.
