- This paper aims to investigate the steady spray characteristics of kerosene and diesel fuel containing dissolved methane. The spray pattern images were captured using a digital camera at the nozzle exit, and the spray droplet sizes were measured using a particle size analyzer (LDSA 1300A) based on the narrow-angle forward-scattering theory. Six types of the straight-hole nozzles with different length/diameter ratios (L/D) were employed in the study. The concentration of methane in liquid fuel was controlled by the dissolving pressure of methane, and the flashing phenomenon produced by the separating dissolved methane was utilized to improve the atomization of the spray. Meanwhile, the parameters, including the spray angle, the Sauter mean diameter, and the discharge coefficient were measured, and the droplet size distribution was fitted using the Rosin-Rammler distribution function. Furthermore, comparison of the spray characteristics between kerosene and diesel fuel with dissolved methane was made. The study reveals that, for a given L/D ratio nozzle, there is the corresponding critical value of methane concentration. When the methane concentration in liquid fuel is larger than the critical value, the liquid fuel atomization is found to improve, whereas below the critical value, the atomization would be suppressed. Moreover, spray angles of liquid fuel containing dissolved methane give smaller values compared to that of pure liquid fuel under lower concentration of methane, but it
will increase dramatically when the concentration is over a certain value. Due to low viscosity, the flashing atomization of kerosene can be improved remarkably with the dissolved methane in fuel compared to that of diesel fuel containing dissolved methane in the case of high methane concentration.
