“…It is worth noting that internal heat generation frequently occurs in the field on nuclear engineering. The absorption of c-rays from the nuclear reactor core is the main reason for such internal energy [37][38][39]. Therefore, a substantial number of publications have been recently published to overcome mathematical challenges in pure conduction systems with internal heat generations [40][41][42][43].…”

Entropy generation is squarely linked with irreversibility, and consequently with exergy destruction within a thermal system. This study concerns with the temperature distribution, and local and volumetric averaged entropy generation rates within a cylindrical system with two solid co-rotating inner and outer parts and the middle nanofluid flow part. Temperature-dependent thermal conductivities for solid materials are included within the modeling. To obtain the temperature formula within all three sections, a combined analytical-numerical solution technique is applied. An exact analytical solution is also obtained, when constant thermal conductivities for solid materials are assumed. The resultant data from the analytical-numerical solution technique is verified against the investigated exact solution. Thereafter, the velocity and temperature fields from the combined analytical-numerical solution technique are incorporated into the entropy generation formulations to obtain the local and volumetric averaged entropy generation rates. Using abovementioned procedure, the effects of thermophysical parameters such as nanoparticles volume concentration, Brinkman number, thermal conductivity parameter ratios, outer temperature boundary condition, internal heat generation rates and velocity ratios on the temperature field, and entropy generation rates are investigated.

“…The absorption coefficient, the Biot number, and the splicing radius were all considered during the research. Goshima and Miyao [111] researched the thermal strains that occur in a hollow cylinder when subjected to x-ray radiation and the heat loss owing to convection. Their study focused on the conditions that occur during temperature transitions.…”

The article investigates the present review of thermoelastic theories of circular and rectangular objects with moving heat sources published on paper after 1950. The main theme of thermoelastic problems on circular and rectangular structures is to establish operational methods to solve governing differential equations. In the thermoelastic problems, we have considered a few practical problems of technical interest, taking into account the circular and rectangular shape geometry with moving heat sources by using integral transform techniques. AMS Subject classifications: 35B07; 35G30; 35K05: 44A10 Keywords: circular and rectangular objects, temperature distribution, thermal stresses, integral transform.

“…Jabbari et al (2007) suggested a general theoretical analysis of three-dimensional mechanical and thermal stresses for a short hollow FGM cylinder by the generalized Bessel function and Fourier series. Goshima and Miyao (1991) analytically solved a long hollow circular cylinder subjected to transient internal heat generation due to x-ray radiation, while there is convection on its inner and outer surfaces. For this purpose, they used Laplace transform and Green's function.…”

“…Most of the literatures have performed the analytical solution of some simple geometries made of FGM, considering simplified assumptions, such as employing Hankel transform (Goshima & Miyao, 1991) or Laplace transform (Sutradhar et al, 2001). In this work, a thick-hollow FGM cylinder subjected to both internal and external pressures and also under thermal loads is solved.…”

This paper presents an analytical and a numerical thermomechanical investigation of a thickwalled cylinder made of the functionally graded materials (FGMs). The hollow cylinder is subjected to a pressure and a thermal load and the properties of this material are varying across the thickness from the inner face that is a ceramic to the outer one which is a metal. After validating the current results by the analytical results, the thermomechanical behavior of the cylinder in the transient condition is investigated and the hoop and radial stresses and also temperature distribution are reported. The results reveal that the use of FG material causes a decrease in the stress; thus, it significantly improves thermomechanical behavior of the domain, thanks to using FG materials.
