“…This heat exchange is the basis of thermal energy storage using porous materials. , A large number of existing porous materials, together with the wide variety of working fluids, make the search for the most appropriate adsorbate–adsorbent pair for each application challenging. Within porous materials, the most common adsorbents for adsorption energy storage are silica gels, ,− zeolites, ,,− metal–organic frameworks, ,− and activated carbons (ACs). − Many of these works have suggested porous materials as great candidates for thermal energy-related applications. However, most of the adsorbents have been studied in laboratories, and they are still not ready for large-scale development at the industrial scale.…”

“…Thermal properties of porous materials are in focus of many ongoing research activities. There has been a growing interest in applying the LFA technique to measure metal and ceramic foams [8,9,10], coal [11], zeolites [12], concrete [13,14] and other promising materials. At the same time, reports exist of thermal conductivity measured in the transient plane source (TPS) method [15] and the guarded hot plate method (GHP) [16] being dependent on the gas chamber atmosphere.…”

“…Among nonharmonic transient techniques of thermal stimulation, laser flash technique (LFT) proposed back in 1961 by Parker et al [41] is the most widely used up to date. It can be easily adopted for testing plate samples of homogeneous [42], anisotropic [43,44], porous [45], translucent [46] solids as well as liquids [47][48][49][50][51][52]. LFT is supported by commercially available equipment [53,54] operating according to established standards [55][56][57].…”

This chapter describes a modification to the laser flash method that allows determining temperature diffusivity and nondestructive testing of materials and constructions without cutting samples of predefined geometry. Stepwise local heating of the studied object surface at a small spot around 0.1 mm radius with simultaneous high temporary-spatial resolution infrared (IR) filming of the transient temperature distribution evolution with a thermal camera provides a wide range of possibilities for material characterization and sample testing. In case of isotropic and macroscopic homogeneous materials, the resulting transient temperature distribution is radially symmetric that renders possible to improve temperature measurement accuracy by averaging many pixels of the IR images located at the same distance from the heating spot center. The temperature diffusivity measurement can be conducted either on thin plates or on massive samples. The developed emissivity independent in plain IR thermographic method and mathematical algorithms enable thermal diffusivity measurement for both cases with accuracy around a few per cent for a wide range of materials starting from refractory ceramics to well-conducting metals. To detect defects, the differential algorithm was used. Subtracting averaged radial symmetric temperature distribution from the original one for each frame makes local inhomogeneities in the sample under study clearly discernible. When applied to crack detection in plates, the technique demonstrates good sensitivity to part-through cracks located both at the visible and invisible sides of the studied object.
