TL;DR: In this article, a simple numerical model, used widely to simulate flame spread over condensed surfaces, called Fire Dynamics Simulator (FDS), has been employed to numerically simulate the experimental cases.

TL;DR: In this paper, a validated comprehensive axisymmetric numerical model, which includes the high pressure transient effects, variable thermo-physical properties and inert species solubility in the liquid phase, was employed to study the evaporation of moving n-heptane droplets within a zero-gravity nitrogen environment, for a wide range of ambient pressures and initial freestream velocities.

TL;DR: In this article, the combustion characteristics of biodiesel produced from karanja oil and its blends with diesel and gasoline were investigated using porous sphere technique, and the visible flame shape was analyzed with the help of digital flame image.

TL;DR: In this paper, the effect of helium release velocities on mixing and distribution of helium within the enclosure, for different quantities of helium released has been experimentally investigated, and the experimental studies are conducted in a test enclosure having a volume of around 2 cubic-meters, specifically designed for the purpose.

TL;DR: In this paper, a comprehensive numerical study of coal dusts in different configurations, by solving the coupled Navier-Stokes and energy equations, provides a clear insight of the thermal field in the coal layer as well as the flow field over the coal surface.
