A numerical study of turbulent flame speeds of curvature and strain G-equations in cellular flows

► We study various G-equation models with cellular flows. ► Numerical schemes are proposed to compute turbulent flame speeds. ► A new reinitialization PDE is proposed for level set functions in periodic domain. ► Curvature and viscosity cause weak and strong front speed bending. ► Strain rate causes incomplete combustion and flame quenching.
