Abstract
The accelerated depletion of oil reserves and the often exorbitant cost of fossil fuels contribute to the development of fuels from renewable sources. The objective of this work is to analyze the influence of the properties of renewable fuels on their evaporation in natural convection, their combustion and their use in internal combustion engines. A summary of the various numerical and experimental works from the literature has been presented in this work. This work focuses on the numerical modelling of the natural convection evaporation of an isolated drop of a liquid fuel in natural convection. The transfers in the liquid and vapour phases are described by the conservation equations of mass and species, momentum and energy. The main feature of this work is the consideration of advection, azimuthal angle and thickness of the vapour phase of the drop during evaporation of the drop.
Highlights
The numerical approach to the problems of evaporation and combustion of fuel droplets has experienced a considerable growth and interest of researchers in recent years [1] [2] [3]
The results show that the distributions of droplet diameter, temperature and mass fraction were found to be strongly dependent on the fuels used
The results show that for both conditions with and without combustion reaction, the droplet lifetime increases with the combustion reaction, with the increase of ambient pressure at a low initial gas temperature of 1000 K, but decreases at the high initial temperatures of 1500 K and 2000 K, the droplet lifetime is shorter due to the combustion reaction
Summary
The numerical approach to the problems of evaporation and combustion of fuel droplets has experienced a considerable growth and interest of researchers in recent years [1] [2] [3] Fuel, injected as a liquid spray, usually burns as a group rather than individually in the diesel engine cylinder It appears that the study of the evaporation of an isolated drop is generally carried out and gives a good first approximation of the evaporation phenomenon [10] [25] [26]. It is necessary to follow the evolution and the influence of the thermal and mass exchanges between the two phases, the influence
