چکیده
The paper presents the large eddy simulation conditional moment closure (CMC) simulation of pilot stabilized methanol flame to study the effects of conditional scalar dissipation rate (CSDR). Two models are used in this research to evaluate CSDR: conditional volume averaging (CVA) and amplitude mapping closure (AMC). For the turbulence modelling, the dynamic Smagorinsky approach is adopted to allow for local adjustment of the Smagorinsky constant. CMC is used for turbulent combustion modeling. CVA is adopted for the calculation of conditional velocity. The temperature, mixture fraction, and major species mass fraction are compared against experimental data along radial direction for both cases. The comparison showed reasonable agreement with the experimental measurements for the temperature. It is also observed that the AMC model is superior in predictions compared to the CVA method. Additionally, carbon monoxide and carbon dioxide are predicted with remarkable accuracy. Moreover, the conditional temperature is also in good agreement with experimental data that shows CMC model capabilities in turbulent combustion modeling.
