Although impressive advances have been achieved in the area of tabulated chemistry for turbulent combustion modeling, table generation remains a tedious task, sometimes as costly as the computation itself. In this work, we intend to offer an alternative to tabulation, applied to the MIL turbulent combustion model. An explicit expression for chemical times, function of pressure, temperature, and mixture fraction (Boivin et al., 2011), is successfully implemented and used instead of tabulated chemistry in the simulation of a supersonic H-2-O-2 lifted flame.
