Local Strain Rate and Curvature Dependences of Scalar Dissipation Rate Transport in Turbulent Premixed Flames: A Direct Numerical Simulation Analysis

Figure 3

Variation of the mean values of ⟨𝑇₁⟩,⟨𝑇₂⟩,⟨𝑇₃⟩,⟨−𝐷₂⟩, and ⟨𝑓(𝐷)⟩ conditional on 𝑐 values across the flame for cases P1, P5, V1, and V3. All the terms of the transport equation of 𝑁_𝑐 are normalised with respect to the respective values of 𝜌₀𝑆²_𝐿/𝛿²_th.
