Abstract

A hyperbolic coupled moisture–heat model is developed by extending the classical Fourier law of heat conduction and Fick’s law of diffusion to investigate the transient hygrothermoelastic behavior in a homogeneous graphite-epoxy resin composite T300/5208 isotropic cylinder with both internal heat and moisture sources. The model addresses the situation where the interior of the cylindrical system is subjected to moisture–heat loading, while its outer surface is insulated and moisture-proof. We employ the Laplace transform and finite Hankel transform techniques to derive the exact solution. The analysis explores the coupling and decoupling effects of temperature, moisture, and stress. The obtained results are useful to engineering applications involving internal heat and moisture sources within cylindrical structures.

利用非傅立叶双曲耦合模型研究具有内部热源和湿源的湿热弹性圆柱体的瞬态响应

采用经典的傅里叶导热定律和菲克扩散定律，建立了双曲型湿热耦合模型，研究了具有内热源和湿源的均匀石墨-环氧树脂复合材料T300/5208各向同性圆柱体的瞬态湿热弹性行为。该模型解决了圆柱系统内部承受湿热载荷的情况，而其外表面是绝缘和防潮的。我们利用拉普拉斯变换和有限汉克尔变换技术推导出精确解。分析探讨了温度、湿度和应力的耦合和解耦效应。所得结果对涉及圆柱形结构内部热源和湿源的工程应用是有用的。

期刊介绍： Case Studies in Thermal Engineering provides a forum for the rapid publication of short, structured Case Studies in Thermal Engineering and related Short Communications. It provides an essential compendium of case studies for researchers and practitioners in the field of thermal engineering and others who are interested in aspects of thermal engineering cases that could affect other engineering processes. The journal not only publishes new and novel case studies, but also provides a forum for the publication of high quality descriptions of classic thermal engineering problems. The scope of the journal includes case studies of thermal engineering problems in components, devices and systems using existing experimental and numerical techniques in the areas of mechanical, aerospace, chemical, medical, thermal management for electronics, heat exchangers, regeneration, solar thermal energy, thermal storage, building energy conservation, and power generation. Case studies of thermal problems in other areas will also be considered.
