    Scaling Analysis on Pulsating Flame Spread over Liquids by Kozue Takahashi, Akihiko Ito, Yuji Kudo, Tadashi Konishi, Kozo Saito

    Published 2008-01-01
    “…Also a nondimensional flame spread rate, V/VD (= Vδ/D, where δ is the quenching distance and D is the diffusivity of fuel vapor) was introduced. Using these nondimensional parameters, the flame spread mechanism was divided into two separate regimes: for the shallow liquid pool the nondimensional flame spread rate was correlated with {Gr0.2/(Ma·Pr)}1.0, while for the deep liquid pool it was correlated with {Gr0.2/(Ma·Pr)}1.5.…”

    Development of universal device for determining the needle stroke in diesel and marine diesel sprayers by L. Yu. Volkova

    Published 2022-02-01
    “…The main malfunctions of diesel and marine diesel injectors with an increase in the needle stroke by more than 50 % of the standard value are described — an increase in the temperature of the nozzle of the sprayer, a breakthrough of cylinder gases into the cavity of the sprayer and the formation of coke, a decrease in the pressure of the injected fuel. A method is proposed for determining the maximum stroke of the needle by measuring the length of the needle shank and its conditional reduction when the needle is placed on the saddle. …”
