“…It should be noted that at large Ɍ 0 the errors of determination of τ ign (do not exceed ± 5 %) go dropping considerably. The established regularities can be explained with the use of hypotheses and models formulated in [7][8][9][10][11][12] according to the results of the performed experiments.…”

“…The general theory of thermal decomposition and ignition charred materials on the organic or polymer-based [8] can be used only when a known constants, characterizing the process of thermal decomposition and thermal properties of its products. The determination of these constants is not less difficult problem compared with the problem of ignition.…”

“…It should be noted that the results of the experimental [7][8][9][10] and theoretical [11][12][13] studies ignition solid [7,9,10] and liquid [11,14] condensed substances (CS) is set to a number of significant features of the ignition mechanisms when local heating arising from the specific heat exposure. Singling out the general regularities of ignition, established in [7][8][9][10][11][12][13][14], we can conclude that the obtained results of experimental studies in inpatient intensive heating of the kinetic parameters of the process do not meet the conditions of local heating of a condensed substance by a source of limited capacity. Therefore, most likely, the induction period during local thermal impact is significantly different from the delay time of ignition under standard conditions [15].…”

Abstract. It is detected, that the main ignition regularities of dispersed wood possible on the basis of experimental studies in terms of the real modes of ignition. The aim of this article is the experimental study of the conditions and characteristics of the single ignition fragments wood the made of dry pine during heating energy intensive metal plate with a constant temperature. The experiments were carried out with particles of wood characteristic sizes. As a result the experimental studies were identified, typical ranges of sample sizes with maximum temperatures of ignition. The results of our experimental studies are the basis for selection of a specific optimization parameters (the temperature of the steel plate and the ignition delay time) when selecting a pulse pyrolysis technologies. Established in experiments regularities allow us to determine fireproof conditions of pyrolytic processes of wood processing in the mode heating pulse for the purpose of biofuel production.

“…Among the well known methods of solving differential equations that describe heat exchange, including methods of finite differences and algorithms for their implementation [5,6], we chose the finite elements method [7], which has demonstrated highly accurate results in the simulation of complex heat exchange. The mathematical model was realized using COMSOL Multiphysics.…”

Abstract. This study examines issues relating to heat exchange between an innovative 6(10) kV current and voltage transformer (and its components) and its environment in unfavourable weather conditions. Existing designs of digital current and voltage transformers are featured in systems of commercial and technical electric power accounting, and also relay protection and automation. We have presented the results of mathematical simulation of the thermal state of both a single resistor included in our measuring device, and the digital transformer as a whole. Simulation was performed using the finite element method. We have taken into account the impact of such factors as direct and diffused solar radiation, high ambient temperatures and various voltage levels on the thermal state of the functioning equipment. To verify the developed mathematical model we have presented the results of a series of experiments conducted in a high-voltage environmental chamber. Our study conclusively shows that voltage, insolation and ambient temperature significantly affect the thermal state of a functioning current and voltage transformer.

“…But these models [6][7][8][9][10][11][12][13] did not explain how ignition characteristics depend on layer thickness. However, the impact of subsurface layer heterogeneity on integral characteristics of ignition was presented in studies [14,15], where structurally inhomogeneous condensed matters were considered.…”

Abstract. Describes the methodology and results of experimental studies of ignition of diesel fuel by a single heated up to high temperatures steel particle. The layer thickness of liquid fuel was changed from 1 mm to 8 mm. It was established dependence of numerical values of the ignition time delay from the thickness layer of diesel fuel. The revealed ignition mode and the limiting layer thickness for diesel fuel when the ignition is missing.
