“…The maximum percentage errors in these quantities are, respectively, 0.06% and 0.15%. Another source of validation of the present results is their comparison with those of [15] when the conductive resistance in the wall-fin assembly is taken to be negligible. This is to note that the results of [15] were obtained using the finite element method with ℎ-adaptivity.…”

“…Due to the complexity and mathematical convenience, in the heat transfer problem, some assumptions were always made relax so that the problem may be explored easily. The assumptions of infinitesimal inner pipe wall thickness and infinite thermal conductivity were considered in [15]. Their investigation presented that the Nusselt number is enhanced more than four times as a result of augmentation of triangular fins.…”

An investigation based on the finite element method for the study of the fluid and the heat transfer characteristics in the triangular FDP heat exchanger with fins of equal height was presented by Syed et al [15]. A uniform heat flux boundary condition (H1) was imposed at the inner pipe.…”

“…In the present investigation, problem [15] is enhanced by taking into account the assumptions of finite thickness of inner pipe wall of FDP and finite thermal conductivity in the inner pipe wall-fin assembly, carried out in chapter 6 of Ph.D. thesis of corresponding author [20]. It may be remembered that in most of the finned annulus fin surface plays a dominant role in heat transfer.…”

A DG-FEM based numerical investigation has been performed to explore the influence of the various geometric configurations on the thermal performance of the conjugate heat transfer analysis in the triangular finned double pipe heat exchanger. The computed results dictate that Nusselt number in general rises with values of the conductivity ratio of solid and fluid, for the specific configuration parameters considered here. However, the performance of these parameters shows strong influence on the conductivity ratio. Consequently, these parameters must be selected in consideration of the thermal resistance, for better design of heat exchanger.

Application of the method of fundamental solutions in combination with the global radial basis function collocation method for analysis of fluid flow and heat transfer in an internally finned square duct is presented in the paper. Fluid flow problem is solved using the modified method of fundamental solutions. After that, the average fluid velocity and product of friction factor and Reynolds number can be determined. Heat transfer problem in the fluid is governed by a nonlinear equation with linear boundary conditions. The Picard iteration method is employed in the paper in order to transform the nonlinear problem into a sequence of inhomogeneous problems. At each iteration step, the general solution is obtained using the modified method of fundamental solutions and the particular solution is obtained using the global radial basis function collocation method. When the iteration process is stopped, the Nusselt number can be determined. Nomenclature aHalf of internal width of channel [m] bThickness of wall [m]
