The object of the present paper is to study temperature distribution and thermal stresses of a functionally graded thick hollow cylinder with temperature dependent material properties. All the material properties except Poisson’s ratio are assumed to be dependent on temperature. The nonlinear heat conduction with temperature dependent thermal conductivity and specific heat capacity is reduced t...

In this study, by using the finite volume method, the heat transfer in a convective straight fin with temperature-dependent thermal properties and an internal heat generation under multi-boiling heat transfer modes are analyzed. In this regard, the local heat transfer coefficient is considered to vary within a power-law function of temperature. In the present study, the coexistence of all the b...

In this study, thermal performance across straight convecting- radiating fin with temperature dependent thermal conductivity is considered. The variation of parameters (VPM) is adopted to analyze the nonlinear higher order differential equations arising due to thermal conductivity and heat transfer coefficient on temperature distribution. Pertinent parameters such as thermo geometric and radiat...

This study describes thermo-rheological properties of branched copolymer surfactants (BCSs) stabilizing oil-in-water emulsions to generate materials exhibiting temperature-dependent gelation with the ability solubilize a broad range molecules. Four poly(N-isopropylacrylamide-ran-poly(ethylene glycol) methacrylate) (poly(NIPAM-ran-PEGMA)) BCSs varying molecular weight (Mn), 4.7; 7.0; 7.8 and 9.0...

A finite element analysis (FEA) model has been constructed to predict the thermo-fluidic and optical properties of a microstructure optical fiber (MOF) accounting for changes in external temperature, input water velocity and optical fiber geometry. Modeling a water laminar flow within a water channel has shown that the steady-state temperature is dependent on the water channel radius while inde...

The generalized Fermi-Dirac thermo-statistics is developed for relativistic nuclear matter. We introduce the generalized thermodynamic potential using the q-deformed exponential and logarithm. The baryon density has a form of the qexpectation value. Then, we use the mapping of the non-extensive thermo-statistics onto the extensive one. Therefore, the Clausius extensive entropy and the physical ...

Generation and dissipation of temperature-induced pore water pressure can alter the mechanical behavior characteristics soil media. Experimental observations indicate that heating/cooling cycles fabric which may result in irrecoverable deformations. Previous studies suggest contribution thermo-osmotic (non-Darcian) flow clays have a significant role thermal pressurization diffusion. Hence, this...

The thermo-optic effect of Si nanocrystals in silicon-rich silicon oxide (SRSO) thin films at 1530 nm is investigated. SRSO thin films, which consist of nanocrystal Si (nc-Si) embedded inside the SiO2 matrix, were prepared by electron-cyclotron-resonance plasma-enhanced chemical vapor deposition of SiH4 and O2 followed by a 30 min anneal at 1150 °C. The refractive indices of all SRSO films incr...
