Abstract
The pressure influence of premixed turbulent flames was studied using the turbulent flame speed closure of Zimont. Calculated results were compared with a data set obtained from experiments under variable pressure conditions from Kobayashi et al. on methane/air Bunsen flames. In this model, an algebraic relation of the turbulent flame speed was used as input in a rather simple but effective form for the prediction of the main flame position in turbulent premixed flames with the help of a mean reaction progress variable approach. The turbulent flame speed relation proposed by Zimont was not directly applicable to include the pressure effect. Also a turbulent flame speed relation proposed by Kobayashi could not be used directly to predict the observed flames within the frame of the TFC approach. Instead, a modified parameterized approach was developed, allowing good prediction of these turbulent methane/air flames at 1-10 bar. Original is an abstract.
