Abstract
An analysis of flame area was performed for DNS database of turbulent premixed flames. A local flame front at a prescribed progress variable was identified as a local three-dimensional polygon. The polygon was divided into some triangles and local flame area was evaluated. The turbulent burning velocity was evaluated using the ratio of the total turbulent flame area to the planar flame area and compared with that obtained by the reaction rate.
