Abstract Adsorption phenomena are encountered in several engineering applications. One of its uses is the storage and transport gas form adsorption tanks. The exothermic nature process decreases capacity presenting an impetus to understand thermal characteristics process. Studies using mixtures phase change materials adsorbents tanks demonstrate potential improvements They also show that distri...

Functionally Graded Materials are inhomogeneous elastic bodies whose properties vary continuously with space. Hence consider a halfspace (x2 > 0) occupied by a special Functionally Graded Material made of an hexagonal (6mm) piezoelectric crystal for which the elastic stiffness c44, the piezoelectric constant e15, the dielectric constant ǫ11, and the mass density, all vary proportionally to the ...
