Modelování úniků a výbuchů uhlovodíků

Abstract

Explosion parameters have been currently published mainly under standard laboratory conditions (20 °C and 101 kPa according to IUPAC). In this paper, maximum explosion pressure, maximum explosion pressure rise rate, deflagration index and laminar burning velocity of propane-air mixture in the maximum flammable range concentrations of 2,0-10,5 % vol. measured at 10°C, 20°C, 100°C and atmospheric pressure and methane-air mixture in the maximum flammable range concentrations of 4,0-15,6 % vol. measured at 25°C, 50°C and atmospheric pressure, are presented. The experimentally obtained values of explosion indices are compared with the mathematical modeling of these gases. The individual aims of diploma thesis are focused on the modeling of explosions due to leaking of flammable substances. The aim of the thesis is to predict and experimentally validate the explosion characteristics of hydrocarbons in combination with visualization of leaks effects for defined initial conditions (concentration, temperature).
