  We propose a predictive model of the turbulent burning velocity over a wide
range of conditions. The model consists of sub models of the stretch factor and
the turbulent flame area. The stretch factor characterizes the flame response
of turbulence stretch and incorporates effects of detailed chemistry and
transport with a lookup table of laminar counterflow flames. The flame area
model captures the area growth based on Lagrangian statistics of propagating
surfaces, and considers effects of turbulence length scales and fuel
characteristics. The present model predicts the turbulent burning velocity via
an algebraic expression without free parameters. It is validated against 285
cases of the direct numerical simulation or experiment reported from various
research groups on planar and Bunsen flames over a wide range of conditions,
covering fuels from hydrogen to n-dodecane, pressures from 1 to 20 atm, lean
and rich mixtures, turbulence intensity ratios from 0.35 to 110, and turbulence
length ratios from 0.5 to 80. The comprehensive comparison shows that the
proposed turbulent burning velocity model has an overall good agreement over
the wide range of conditions, with the averaged modeling error of 25.3%.
Furthermore, the model prediction involves the uncertainty quantification for
model parameters and chemical kinetics to extend the model applicability.
