Abstract
Subject headings
Close
- The DNS and the conditionally filtered LES (CFLES) were combined to examine the validity of the linear-diffusion approximation and the first-order closure in CFLES equation. The linear-diffusion approximation was applied to closing transport term in mixture-fraction space in CFLES equation, and the first-order closure was used in closing conditionally filtered reaction source term. The first two order moments of filtered mass-fraction of the reactant were obtained by using CFLES and were closed to results of the DNS, which well examined the validity of the approximations mentioned above.
