Thermal investigation of fully wet longitudinal porous fin of functionally graded material

Abstract

Purpose The purpose of this study is to conduct a numerical computation to analyse the thermal attribute and heat transfer phenomenon of a fully wetted porous fin of a longitudinal profile. The fin considered is that of a functionally graded material (FGM). Based on the spatial dependency of thermal conductivity, three cases such as linear, quadratic and exponential FGMs are analysed. Design/methodology/approach The governing equations are nondimensionalised and solved by applying Runge-Kutta-Fehlberg fourth-fifth order technique. Findings The parametric investigation is executed to access the significance of the pertinent parameters on the thermal feature of the fin and heat transmit rate. The outcomes are portrayed in a graphical form. Originality/value No such study has yet been published in the literature.

Continuous composite longitudinal fins under oscillating boundary conditions: a lattice Boltzmann solution

“…Enhancement of heat transfer process by means of fins are more economical and power-saving approach. For Engineering Computations extended surface, in the pursuit of enhancing the heat dissipation density, researchers have explored the area of porous fin (Darvishi et al, 2016;Gireesha et al, 2019;Sowmya et al, 2020;Turkyilmazoglu, 2017) and variable fin geometry design (Cotta and Ramos, 1998;Moitsheki and Harley, 2011;Mosayebidorcheh et al, 2014;Vyas et al, 2019). On the other hand, fabricating highly conducting materials can also open the opportunity for designing highly heat-dissipating extended surfaces.…”

Numerical simulation of heat and mass transfers radiative–convective fluid flow on a stretching porous surface with temperature‐dependent thermophysical properties

“…In another study, the thermal performance of a fully wet longitudinal porous fin with thermal conductivity, surface emissivity, and heat transfer coefficient depending on temperature was examined by Sowmya et al 45 Gireesha et al 46 studied the analysis of the thermal behavior of moving longitudinal porous fin wetted with water‐based SWCNTs and MWCNTs. Sowmya et al 47 studied the thermal exploration of radial porous fin fully wetted with SWCNTs and MWCNTs along with internal heat generation depending on temperature. Onwubuoya and Dada 48 studied Soret, viscous dissipation, and thermal radiation effects on MHD free convective flow of Williamson fluid by varying viscosity and thermal conductivity.…”

Shape effect of nanoparticles on MHD nanofluid flow over a stretching sheet in the presence of heat source/sink with entropy generation

“…The convection effect on the vertical stretched surface was analyzed by Wang (1989), whereas the nonlinear stretching sheet has been presented by Hayat et al (2009) and Xu and Lee (2013). Some of the significant work can be found in Lewis et al (2006), Nithiarasu et al (2008); Bevan et al (2012), Gireesha et al (2019); and Sowmya et al (2020) Studies related to the impact of spherical and non-spherical nanoparticles on heat transfer enhancement of nanoliquid do have a broad range of applications in engineering and industries. It is noteworthy that nanofluids' thermo-physical characteristics do vary with the alteration in types, size, shape, size, base liquid and volume fraction of nanosized particles.…”
