The low temperature radiant systems are very complex because they involve different mechanisms of heat transfer: heat conduction through the walls, heat convection between the heating panel and the indoor air, heat radiation between the heating panel and the surrounding areas, and the heat conduction between the floor and the ground. The main essence of the low-temperature air systems is to pro...

Predictive modelling of turbulent combustion is important for the development of air-breathing engines, internal combustion engines, furnaces and for power generation. Significant advances in modelling non-reactive turbulent flows are now possible with the development of large eddy simulation (LES), in which the large energetic scales of the flow are resolved on the grid while modelling the eff...

Thermal ionization of alkali species emitted from thermally decomposing vegetative matter into the combustion zone of a fire makes the zone a weakly ionized gaseous medium. Collision between the medium electrons and neutral flame particles is a dominant form of particle interaction and incident microwave energy absorption process. Electromagnetic wave absorption properties of vegetation fire ha...

A new approach for gas-phase combustion synthesis of nanosized particles using a novel hybrid burner facility is demonstrated. The basis of the synthesis technique is to use both a premixed flame and a diffusion flame to control the synthesis environment. Specific experimental results for silica (SiO2) production from silane/hydrogen/ oxygen/argon (SiH4/H2/O2/Ar) flames are presented. A paramet...

New laminar burning velocity measurements of 85:15% (by volume) H2–CO and H2–N2 mixtures with O2–He oxidizer are reported at lean conditions and elevated pressures (1–10 atm). Experiments are conducted using the heat flux method at initial temperature of 298 K. In this technique a near adiabatic flame is stabilized by balancing the heat loss from the flame to the burner with heat gain to the un...

ion via reaction (647) is dominant, due to its low activation energy, up to 0.4 cm above the burner while reaction (644) becomes dominant farther from the burner. Reaction with OH to give phenol, i.e., reaction (652), does not contribute significantly to benzene depletion while the reverse reaction even leads to benzene formation close to the burner. Benzene formation in the acetylene flame res...

The article discusses the express method proposed by authors for experimental measurement of mass burnout rate liquid combustible substances. Describes experiments carried out with various liquids, which impregnated products made porous heat-resistant material in form spheres or flat cylindrical "tablets" different diameters. These were placed on digital scales and set fire. A video camera conn...
