“…When the temperature reached 130 ~ 180 o C, strong nucleate boiling phenomenon occurred, which resulted in a quick disappearance of the liquid film. Lepperhoff et al [19] and Hsieh et al [20]observed film boiling at surface temperatures beyond the Leidenfrost point. The presence of the gas film hindered the direct contact between the liquid film and the wall surface, which was favorable towards reducing the carbon deposits.…”

“…Moreira et al [21,22] also developed an empirical correlation to describe the heat transfer process in a simulated gasoline spray experiment. Hsieh et al [23] reported that a lower temperature surface led to faster growth of the deposit area in a spray burner. Montanaro et al [24] found that at first the increase of impinging surface temperature could decrease the spread of the liquid film but further increases beyond the Leidenfrost point caused an increased spread.…”

Fuel spray impingement on piston surfaces is a concern because it can cause particulate exhaust emissions from gasoline direct injection (GDI) engine. Transient heat transfer plays an important role that directly influences liquid film evaporation and its lifetime. In this paper, the effects of injection temperature, injection pressure, piston temperature and impact distance on n-pentane spray impingement heat transfer were fully examined. Results showed that increasing the piston temperature could increase the rate of heat transfer with a larger surface temperature reduction and a higher heat flux, which led to a shorter liquid film lifetime on the piston surface. Increasing the fuel injection temperature helped to improve atomization of the fuel spray, reduce the penetration distance and mitigate impact, which in turn led to reduced surface cooling and less liquid film on the piston surface. A decrease in impact distance and an increase in injection pressure both caused an increase in surface temperature reduction and heat flux but a decrease in the liquid film residence time. The dimensionless heat flux in terms of Biot and Fourier numbers presented a high similarity during the rapid cooling stage. A dimensionless correlation was formed to quantify this fast time-varying heat transfer behaviour.
