Time-fractional hygrothermoelastic analysis of nanocomposite cylinder subjected to hygrothermal loadings.

This study aims to investigate time-fractional transient heat and humidity transfer in nanocomposite media subjected to hygrothermal loadings. After each layer has been subjected to time-independent volumetric heat sources and hygrothermal loadings at the cylindrical surfaces, the resulting hygrothermal field is analyzed and characterized. In contrast to previous analytical research, even the effects of moisture on heat transport are ignored. When defining a temporal coupled issue, the presence of exact progression in dampness flux at layer interfacing holds on. This is the case even though moisture-induced effects on heat transfer are ignored. The analytical solution to the hygrothermal field can be obtained by employing a method of integral transformation, which is analogous to the Sturm-Liouville change for the composite region of k-layers by taking into account series extension function with eigenfunction to solve the partial differential equations. This allows the problem to be transformed into a form that can be solved analytically. The impact of moisture-flux progression at the layer interface on the dissemination of hygrothermal stretch is examined utilizing numerical reenactments for a three-layered structure, and the comes about are outlined graphically.
