This work covers the effect of droplet deformation on its evaporation rate under convective flow conditions. The behavior a freely deforming single component jet fuel surrogate, n-decane, is investigated by varying Weber number ($We$) from $1-12$ and Reynolds ($Re$) $25$ to $120$ high-pressure environment. These studies utilize interface capturing Direct Numerical Simulation (DNS). To validate ...

In this paper, a non-isothermal two-phase flow in the cathode gas diffusion layer (GDL) of PEM fuel cell is modeled. The governing equations including energy, mass and momentum conservation equations are solved by numerical methods. Also, the optimal values of the effective parameters such as the electrodes porosity, gas diffusion layer (GDL) thickness and inlet relative humidity are calculated...

The environmental impact of spills of JP-8, a kerosene-based jet fuel, has been studied very little. For the more volatile JP-4, earlier studies showed that biodegradation was less important than evaporation but for JP-8, evaporative loss from soil is very slow. Disappearance of JP-8 from watered mesocosms was monitored over several months. In two, 10-cm wide x 35-cm deep x 180-cm long channels...

The potential of Palm Methyl Esters (PME) as an alternative fuel for gas turbines is investigated using a swirl burner. The main air flow is preheated to 623 K and a swirling spray flame is established at atmospheric pressure. The spray combustion characteristics of PME are compared to diesel and Jet-A1 fuel under the same burner power output of 6 kW. Investigation of the fuel atomizing charact...

Residual fuel oil spilled into the sea from the Eshkol power station on 8 February, 1998 contaminated about 9 km of the foreshore north of the Ashdod harbour. A study of the aliphatic, polycyclic alkane and polyaromatic hydrocarbon (PAH) composition of the spilled oil shows rapid weathering in the early stages followed by gradual slowdown after about three months. Weathering of isoprenoids and ...

INTRODUCTION The different volatility of the components of a fuel mixture will result in different vaporization rates of components at the droplet surface, and the fuel becomes non-uniform inside the liquid phase because of the mass diffusion resistance inside the droplet. For practical, multidimensional simulations of IC engines, zero-dimensional models for the liquid phase are necessary becau...
