“…As the parameter rises, there is an increase in the permeability of the fin medium, leading to better movement of ambient fluid and dip in fin tip temperatures. The thermal efficiency of exponential fin structures for distinct values of fin shape parameter ν for both insulated and convective boundary conditions has been depicted in Figures 16,17,and 18. The influence of wet porous parameter m 2 , thermal conductivity parameter B, and angle of inclination ψ on thermal fin efficiency has also been represented respectively in Figures 16,17 F I G U R E 16 Repercussion of wet porous parameter m 2 and fin shape parameter α on fin efficiency for insulated and convective tip conditions.…”

A convective‐radiative fully wet porous inclined longitudinal fin of exponential profile is the focus of the current work. The thermal behavior of the fin under unsteady conditions has been analyzed for adiabatic and convective boundary conditions. The exponential fin and its counterpart inverted exponential fin are simultaneously investigated by considering temperature‐relevant thermal conductivity and heat generation. The modeled governing equation upon nondimensionalization reduces to a partial differential equation which is computed by employing the finite difference approach. The impact of relevant parameters like the convective parameter, radiative parameter, wet porous parameter, dimensionless time, exponential index, dimensionless ambient temperature, generation number, thermal conductivity parameter, and angle of inclination on thermal characteristics of exponential and inverted exponential fin structures with adiabatic and convective boundary restrictions have been examined. One of the main outcomes was that the inverted exponential fin with an adiabatic tip gives rise to the highest thermal curve, and the tapered exponential fin with a convective tip resulted in the lowest thermal curve.

“…The impact of stretching/shrinking on the heat transport rate and temperature of tapered exponential and inverted exponential profiles was discussed by Gireesha et al 14 The shrinking mechanism was reported to enhance the heat transport rate. Further, works by Khan et al [15][16][17][18][19] play a significant role in the analysis of heat transfer enhancement.…”

Studying the effect of the force convection boundary condition and radius magnetic field on fluid flow and heat transfer between coaxial pipes

et al. 2023

An investigation of the heat transfer of Newtonian fluid flow through coaxial two pipes with variable radius ratio has been conducted with the boundary conditions of forced convection on the inner pipe walls and a radius magnetic field. This paper presents an exact analytical solution to the momentum equation and a novel semi‐analytic collocation method for solving the full‐term energy equation that takes Joule heating into account as well as viscous dissipation. Based on the results of the numerical fourth‐order Runge–Kutta method, it was found that increasing the magnetic parameter decreased the amount of friction on the surface of the pipe walls and the rate of heat transfer. As the radius ratio of the two pipes increases, so does the skin friction and heat transfer rate on the internal pipe walls. As Eckert (Ec) and Prandtl (Pr) numbers increase, the mean temperature as well as the dimensionless temperature between the two pipes increases. The increase in Biot number (Bi) has the opposite impact on the mean temperature. As Ec, Pr, and Bi increase, so does the rate of heat transfer on the inner wall of the pipe.
