Reduced Combustion Mechanism for Fire with Light Alcohols
نویسندگان
چکیده
The need for sustainable energy has incentivized the use of alternative fuels such as light alcohols. In this work, reduced chemistry mechanisms prediction fires (pool fire, tank and flash fire) two primary alcohols—methanol ethanol—were developed, aiming to integrate detailed kinetic model into computational fluid dynamics (CFD) model. accommodates either pure reactants products or other intermediates, including soot precursors (C2H2, C2H4, C3H3), which were identified via sensitivity reaction path analyses. developed mechanism was adopted predict burning behavior in a 3D domain estimation product distribution. agreement between experimental data from literature estimations resulting analysis performed work demonstrates successful application method integration CFD models, opening an accurate evaluation safety scenarios allowing proper design storage transportation systems involving

From fire whirls to blue whirls and combustion with reduced pollution.
Fire whirls are powerful, spinning disasters for people and surroundings when they occur in large urban and wildland fires. Whereas fire whirls have been studied for fire-safety applications, previous research has yet to harness their potential burning efficiency for enhanced combustion. This article presents laboratory studies of fire whirls initiated as pool fires, but where the fuel sits on ...
متن کاملOxygen-flask combustion with light beam ignition.
A robust oxygen-flask combustion system was developed using light beam ignition. An appropriate amount of environmental sample was wrapped with a small piece of filter paper and held in a basket made of platinum-zirconium spiral. After the sample was inserted into an oxygen-filled flask containing an acid mixture, the light beam from an overhead projector lamp was focused to ignite the sample. ...

Several agents are under consideration to replace CF3Br for use in suppressing fires in aircraft cargo bays. In a Federal Aviation Administration (FAA) performance test simulating the explosion of an aerosol can, however, the replacements, when added at sub-inerting concentrations, have all been found to create higher pressure rise than with no agent, hence failing the test. Thermodynamic equil...
