“…It could be said that the inlet velocity presented in Table 1 is close to the lowest value ensuring a stable burner operation. Indeed, the macroscopic thermal wave can propagate within the matrix on a time scale of 10 1 e10 2 s although the phenomena at the pore scale are unsteady and local fluctuations are observed [21]. The analysis first emphasizes phenomena at the macroscale such as the flame structure, heat recirculation and flow in the burner.…”

“…They observed a decrease in H 2 production and an increase in CO production as CO 2 was added to a rich methane-air mixture. With the 3D model approach, either a single column [20,23] or an entire burner [21,22] can be modeled. In both cases, the approach has the advantage of capturing small-scale phenomena such as spatial velocity fluctuations, a task that is not possible with the volumeaveraged method.…”

“…In both cases, the approach has the advantage of capturing small-scale phenomena such as spatial velocity fluctuations, a task that is not possible with the volumeaveraged method. For example, Yakolev and Zambalov [21] modeled a 3D random packed spheres burner with a rich methane-air mixture having a 4 of 2.5. Observations at the pore scale revealed large spatial variations of the temperature and velocity fields due to the inhomogeneity of the matrix.…”

“…The authors of [27] show the influence of small defects on the fatigue strength of martensitic stainless steel; the propagation of waves in deformable media and the interaction of two deformable media under dynamic loads were not investigated. In [28], three-dimensional numerical simulation of methane and air combustion in inert porous media on a pore scale under conditions of propagation of the combustion wave in the medium up and downstream is reported but there are no results of studies into wave propagation in deformable media and the interaction of two deformable media under dynamic mobile intense loads. There is no accounting for wave processes in deformable media and the interaction of two deformable media under dynamic mobile loads, thus the essential strength characteristic of the structure was disregarded.…”

Materials of beams, plates, slabs, strips have been commonly applied in various fields of industry and agriculture as flat elements in the structures for machinery and construction. They are associated with the design of numerous engineering structures and facilities, such as the foundations of various buildings, airfield and road surfaces, floodgates, including underground structures. This paper reports a study into the interaction of the material (of beams, plates, slabs, strips) with the deformable base as a three-dimensional body and in the exact statement of a three-dimensional problem of mathematical physics under dynamic loads. The tasks of studying the interaction of a material (beams, plates, slabs, strips) with a deformable base have been set. A material lying on a porous water-saturated viscoelastic base is considered as a viscoelastic layer of the same geometry. It is assumed that the lower surface of the layer is flat while the upper surface, in a general case, is not flat and is given by some equation. Classical approximate theories of the interaction of a layer with a deformable base, based on the Kirchhoff hypothesis, have been considered. Using the well-known hypothesis by Timoshenko and others, the general three-dimensional problem is reduced to a two-dimensional one relative to the displacement of points of the median plane of the layer, which imposes restrictions on external efforts. In the examined problem, there is no median plane. Therefore, as the desired values, displacements and deformations of the points in the plane have been considered, which, under certain conditions, pass into the median plane of the layer. It is not possible to find a closed analytical solution for most problems while experimental studies often turn out to be time-consuming and dangerous processes

“…The latter device is of significant importance, both theoretically and practically. Combustion process in porous burners has been studied extensively [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29], using both experimental and numerical modelling methods, with respect to different burner configurations, combustion regimes and employed fuels (for example, biofuels). Recently Arutyunov et al [30], using numerical methods, investigated nature of the upper limit of methane-air mixture combustion on a flat porous lattice.…”

Stabilization of planar premixed flame front on a lattice (porous) burner is considered. It is rigorously mathematically proved that there exist two different stabilization regimes: one with flame front located nearby the surface of the burner, and another with flame front located inside the lattice. These two regimes result in qualitatively different gas temperature profiles along the flow, that is monotonic and non-monotonic, respectively. Boundary between the two regimes is described in terms of dependence of the lattice solid material temperature on flow Peclet number. Likewise temperature profiles, such dependencies may be both monotonic and non-monotonic. Transition between the two types of dependencies is controlled by Arrhenius number. Conclusions of the study are supported by numerical analysis. They also compare favourably with available experimental data. Novelty of the present approach is fundamentally rigorous analytical analysis of the problem.
