The liquid spray angles of the n-heptane/3-pentanone mixture under both conditions are larger than the other two fuel mixtures, which is hypothesized to be attributed to less vaporization due to its larger latent heat of vaporization as shown in Table 7.
Vaporization of n-heptane/3-pentanone mixture spray appears to be slower than n-heptane and n-heptane/DEMA/fluorobenzene mixture, as evidenced by the liquid spatial distributions after 1.8ms ASOI under both 452 K and 680 K ambient conditions, which is related to the larger latent heat of vaporization by introducing 3-pentanone into the mixture.
With the cooling turned off, a higher fuel temperature leads to faster fuel vaporization, which creates transitions along the spray edge that is commonly seen in sprays under 680 K condition with cooling turned on.
The differences towards the end of the hydraulic duration at 1 ms and after 2 ms indicate that differences exist in the vaporization and mixing of the spray.
* Vaporization: n-heptane spray vaporizes faster than E10 Gasoline and the multi-component E10 surrogate, under both the 452 K and 680 K ambient condition, while the vaporization of the E10 Gasoline and the multi-component E10 surrogate are similar.
* Spray penetrations: the penetrations of the surrogate mixtures with and without tracers generally follow each other well, with the exception that n-heptane/3-pentanone mixture has longer liquid penetrations than n-heptane and n-heptane/DEMA/fluorobenzene mixture after 2 ms in the liquid phase, which is hypothesized to be caused by differences in fuel vaporization.
* Spray angles: with slower vaporization of n-heptane/3-pentanone, its liquid spray angle is larger compared to the other two mixtures using n-heptane as the base fuel.
* Vaporization: slower vaporization of n-heptane/3-pentanone mixture is observed compared to n-heptane and n-heptane/DEMA/fluorobenzene mixture.
