In the current paper a new approach is provided for prediction of Lean blow out, based on combining cold flow numerical simulations with test results in a particular combustion chamber based on loading parameter. Two approaches are presented to calculate these parameters using Ansys Fluent software. In the first method, only the species transport motif and in second method, the evaporation and atomization of kerosene fuel have been implicated to achieve more accurate results. Finally, the results of these two methods and also a code based on semi-empirical model were compared with experimental results. The errors of the semi-empirical code, first and second numerical methods were obtained as 46.73, 11.48 and 1.86, respectively.
