Fundamental experiment on vapor explosion with mass of grains.

Vapor cloud explosion analysis of onshore petrochemical facilities

The paper describes an approach to predicting gas explosion loads and response which has been developed for offshore installations and which only recently has been adapted to onshore petrochemical facilities. The paper consists of three parts: Part 1: An overview of vapour cloud explosion hazards in petrochemical onshore facilities and a discussion of modeling approaches. Part 2: A probabilisti...

Presupernova evolution and explosion of massive stars with mass loss

We review the main properties of solar metallicity massive stars in the range 11-120 M⊙. The influence of the mass loss on the hydrostatic burning stages as well as the final explosion is discussed in some detail. We find that the minimum masses that enter the WNL, WNE and WC stages are 30 M⊙, 35 M⊙ and 40 M⊙ respectively; the limiting mass between stars exploding as SNII and SNIb/c is between ...

Methods of Quantifying and Mitigating Aerosol Fire and Explosion Hazards Associated with Low Vapor Pressure Liquids

This paper addresses the hazards associated with aerosolized hydraulic fluids and other liquids designed to be relatively non-flammable with respect to flashpoint and vapor pressure. The studies presented seek to understand and quantify conditions and circumstances that can produce such hazardous conditions. US Navy personnel are particularly susceptible to fuel aerosol hazards due to the wides...
