Results have been validated with experimental data provided by SANDIA laboratories, conducted at different operating conditions and with different fuels. The comparison is made in terms of typical parameters such as liquid penetration length, the flame lift-off and the ignition delay time.Results&nbsp; indicated&nbsp; that&nbsp; there&nbsp; are&nbsp; a&nbsp; good&nbsp; concordance &nbsp;between&nbsp; CFD&nbsp; simulation&nbsp; and experimentation, when each surrogate fuel is compared. Nevertheless, when they were compared&nbsp; to&nbsp; D2&nbsp; fuel,&nbsp; the&nbsp; n-heptane&nbsp; was&nbsp; the&nbsp; surrogate&nbsp; that&nbsp; best&nbsp; matched&nbsp; the&nbsp; D2&nbsp; fuel behavior, in terms of Lift-Off length and ignition delay time.</p><p>&nbsp;</p> ER -
