Turbulent Flame Speed Can Increase under Curvature Smoothing
Hung V. Tran, Jack Xin, Yifeng Yu
Curvature effects are expected to smooth flame-front wrinkles and thereby reduce turbulent flame speed. We construct a smooth three-dimensional periodic shear flow for which introd…

Does Yakhot's growth law for turbulent burning velocity hold?
Wenjia Jing, Jack Xin, Yifeng Yu
Using formal renormalization theory, Yakhot derived in ([32], 1988) an growth law of the turbulent flame speed with respect to large flow in…
