“…Ghuri et al [17], Jankowski et al [18], and Chen et al [19] investigated the effect of injection pressure and fuel type on various spray characteristics such as penetration length, spray cone angle, and droplet size distribution. In particular, they observed that high viscosity fuels produced longer penetration length and bigger droplet sizes.…”

High-speed planar laser Mie scattering and Laser Induced Fluorescence (PLIF) was employed for the determination of Sauter Mean Diameter (SMD) distribution in non-evaporating diesel sprays. The effect of rail pressure, distillation profile, and consequent fuel viscosity on the drop size distribution developing during primary and secondary atomization was investigated.Samples of conventional crude-oil derived middle-distillate diesel and light distillate kerosene were delivered into an optically accessible mini-sac injector, using a customized high-pressure common rail diesel fuel injection system. Two optical channels were employed to capture images of elastic Mie and inelastic LIF scattering simultaneously on a high-speed video camera at 10 kHz.Results are presented for sprays obtained at maximum needle lift during the injection. These reveal that the emergent sprays exhibit axial asymmetry and vorticity. An increase in the rail pressure was observed to lead to finer atomization, with larger droplets observable in the neighbourhood of the central axis of the spray, decreasing with radius towards the spray boundaries. Finally, the light kerosene was observed to produce smaller droplets (as measured by Sauter mean diameter), relative to the conventional diesel, suggesting a correlation between distillation profile and viscosity, and mean spray droplet size.

“…This operation is carried out under pressure, usually at p % (15-50) MPa and moderate temperature T % (300-350) K, and is strongly affected by the fuel density [3][4][5]. With the common rail injection technology the pressure can reach up 100-120 MPa [6,7]. Therefore the simulation of biodiesel production, blending, and design of injection systems requires accurate knowledge of volumetric properties over wide ranges of pressure and temperature.…”

“…Palani et al [5] concluded that the spray field is significantly influenced by the injection pressure based on an examination of all spray parameters. Ghurri et al [6] conducted an experimental study and the result shows that the spray is produced more quickly and it penetrates faster under a higher injection pressure. The majority of the research were conducted under steady conditions with constant inlet pressures and constant injected mass flow rates.…”

Numerical Study of the Effects of Injection Fluctuations on Liquid Nitrogen Spray Cooling

et al. 2019

Spray cooling with liquid nitrogen is increasingly utilized as an efficient approach to achieve cryogenic cooling. Effects of injection mass flow rate fluctuations on the evaporation, temperature distribution, and droplet distribution of a spray field were examined by employing a validated Computational Fluid Dynamics (CFD) numerical model. The numerical results indicated that injection fluctuations enhanced the volume-averaging turbulent kinetic energy and promoted the evaporation of the whole spray field. The strengthened mass and heat transfer between the liquid nitrogen droplets and the surrounding vapor created by the fluctuating injection led to a lower temperature of the whole volume. A relatively smaller droplet size and a more inhomogeneous droplet distribution were obtained under the unsteady inlet. The changes of the frequency and the amplitude of the fluctuations had little effects on the overall spray development. The results could enrich the knowledge of the relation between the inevitable fluctuations and the overall spray development and the cooling performance in a practical spray cooling system with cryogenic fluids.
