Nowadays there are many software tools available which, in case of a gas release, allow to calculate the dispersion of the gases (and hence predict the size and shape of the cloud) and to calculate the overpressures as a function of distance if this gas cloud should explode. The next step is then to predict what the consequences of these overpressures will be: to what extent will buildings (and...

By adding water to fuels, several objectives are pursued, with the main ones being stabilize combustion, minimize anthropogenic gaseous emissions, homogenize and fuel, as well improve its fire explosion safety. Water can be injected into furnace droplets or vapor introduced part of fuel samples. often serves a coupling carrier medium for delivery components. In this paper, we compare combustion...

The microscopic mechanisms of femtosecond laser ablation of an Al target are investigated in large-scale massively parallel atomistic simulations performed with a computational model combining classical molecular dynamics technique with a continuum description of the laser excitation and subsequent relaxation of conduction band electrons. The relatively large lateral size of the computational s...

The Wagner equation for prediction of vapor pressure has been modified in order to improve it accuracy. On the basis of this modifications, development of a new equation for prediction of vapor pressure is outlined. Examples of the use of the equation for obtaining vapor pressure for a total of 94 pure substance are given. The proposed equation combines simplicity and accuracy and performs as w...

explosion has always been regarded as one of the most complicated engineering problems. as a result, many engineers have preferred rather simplified empirical approaches in comparison to extremely complex deterministic analyses. in this paper, however, a numerical simulation based on the combined finite/discrete element methodology is presented for analyzing the dynamic behavior of fracturing r...

An experimental study on maximum explosion pressure in closed vessel deflagration of stoichiometric gaseous mixtures, for various initial pressures within 0.3 – 1.2 bar and ambient initial temperature is reported. Explosion pressures and explosion times of stoichiometric methane-, ethaneand propane-air mixtures were measured in a spherical vessel and in two cylindrical vessels with different di...
