A131 層流燃焼速度を考慮した渦消散モデルの導出(燃焼科学と技術の新展開III)
詳細
The eddy dissipation model (EDM) can be used with RANS model. However, a typical EDM uses only the time scale of RANS model as the time scale of reaction. Therefore, an EDM cannot be applied for the wrinkled flame in premixed flame. For example, the laminar burning velocity affects the turbulent burning velocity. Proposed in this paper is an EDM which includes the laminar burning velocity. When turbulence strength is high, time scale of the new model approaches that of the original EDM. When the turbulence strength is low on the other hand, flame described by the new model propagates with the laminar burning velocity.
