    Determination of the temperature conductivity coefficiency of bulk biofuels
    (2021) Volchok, V. O.
    The article presents the results of the experimental determination of the temperature conductivity coefficient of bulk fuel of plant origin. Solid bulk materials formed by solid and gas phases are widely used in human economic activities. The quality indicators of heterogeneous materials and products made from them are often determined by heat transfer modes, which depend on thermophysical properties: thermal conductivity, heat capacity, thermal diffusivity. These properties are functions of the properties of its solid and gas phases, pore volume or space between solid particles and the specific volume of the solid phase, etc. This leads to a significant effect on the thermophysical properties of mechanical, thermal and physicochemical effects that materials are exposed to during operation. Therefore, the solution of the problems of developing calculation methods and experimental determination of the properties of heterogeneous materials, taking into account their structural characteristics, is of particular relevance. Thus, the problem of controlling the thermophysical properties of heterogeneous materials which are formed by solid and gas phases, and which are subject to mechanical, thermal, physicochemical effects during operation, is of current interest. The paper presents a method for measuring thermophysical properties based on the use of a regular regime of the first kind at various stages of the measurement process.
