The validation of an evaporative spray simulation with LES has been conducted using Rayleigh scattering method. Rayleigh scattering method is able to measure the instantaneous equivalence ratio on the spray cross section, assuming adiabatic mixture between ambient gas and fuel to estimate the mixture temperature. It is used to validate an evaporative spray simulation with LES. The results showed that the LES simulation was possible to reproduce the evaporative spray development in the quasi-steady condition, using the finer computational grid. In order to improve the computational accuracy, the radial development of the gas velocity from the spray upstream should be reproduced by the improvement of the computational scheme and the spray modeling.
