The theory on thermal explosions according to Semenov’s approach is thoroughly described in this chapter. The main calorimetric tests to be carried out for a safe thermal analysis are also reported. The thermal inertia is defined and its effects on the characterization of reactive chemical systems is evaluated.

Fragmentation in thermal explosions
International Journal of Heat and Mass Transfer, 1974Abstract A series of experiments involving explosions between molten tin and water is described. The results, together with information from other work, indicate that thermal explosions usually involve several distinct interactions in the same mass of material, and that each interaction forms a bubble containing some vapour whose collapse initiates ...

The thermal initiation of explosion in liquid explosives
Symposium on Combustion and Flame, and Explosion Phenomena, 1948The effect of many stimuli on explosives is probably ultimately reducible to an effect of heat. It has been customary to measure the sensitiveness of explosives to heat by determining an "ignition temperature," and the assumption is frequently made that this has a definite value, like the melting point, although wide variations are apparent in the ...

Thermal Initiation of Explosives
Journal of Applied Physics, 1960Numerical solutions have been obtained for the nonlinear heat conduction equations arising in the theory of thermal explosions. Explosion times are calculated for externally heated spheres, cylinders, and slabs of several explosive materials, and the results are shown to agree with experiment.

Thermal explosions with variable thermal conductivity
Canadian Journal of Chemistry, 1982Numerical solutions are presented for the case of a thermal explosion in a sphere, in which the thermal conductivity varies linearly with temperature. The behaviour of the critical temperature profiles and of the other critical parameters for variations in the thermal conductivity are demonstrated.

Thermal runaway in the thermal explosion of a liquid
Journal of Thermal Analysis, 1984To study the thermal explosion of liquids a low pressure autoclave has been built. The first stage of a thermal explosion, the thermal runaway, has been studied. Evaluation of the temperature-time history results in kinetic data. Comparison with other thermal methods shows that the reliability of the method is better than with DTA.

Thermal hazard assessment of AN and AN-based explosives
Journal of Hazardous Materials, 2003Ammonium nitrate (AN) is an essential ingredient in most fertilizers. It is also widely used in the commercial explosives industry. In this latter application, it is mostly mixed with fuel oil to form the most popular commercial explosive: ANFO. In both the fertilizer and the explosive industry, aqueous AN solutions (ANS) of various concentrations are ...

Theory of chemical fluctuations in thermal explosions
Physical Review A, 1985Autoignition phenomena in combustion problems exhibit a remarkable random behavior. We show on a simple model of an exothermic reaction that the phenomena has strong analogies with the transient behavior of a chemical explosion (Malthus model). These analogies lead to the construction of a simple theory of fluctuations.
