“…The hydraulic and thermal performance of the optimum configurations has been evaluated by appropriate performance measures, and various optimum configurations have been proposed according to different concerns of the designers. In [7][8][9], optimum configurations were investigated by considering the Nusselt number as an objective function. A comparison of the optimum configurations based on both of these objective functions for both types of characteristic lengths has been given.…”

Optimum configurations of the parabolic finned annulus have been investigated for maximum convection by employing a genetic algorithm. The objective of the work is to enhance the heat transfer rate and minimize the pressure loss in the flow direction for optimum use of thermal energy and savings of cost. Flow is considered to be steady, laminar, incompressible, and fully developed, subjected to the constant heat flux boundary condition imposed at the finned inner pipe, made up of highly conductive material. A comparison of the present optimum configurations has been carried out with those based on the Nusselt number as an objective function. The results indicate that the present objective function gives, in many cases, cost-and weight-efficient optimum configurations with considerable reduction in pressure loss and provides optimum use of thermal energy along with handsome savings of cost. A comparison of the present optimum configurations of parabolic fins has also been carried out with those of trapezoidal and triangular fins. The results indicate that no single shape is best in all the situations and for all the criteria. The performance evaluation and comparison led to some very interesting findings regarding the configurations of the finned annulus and the choice of the objective function. The local results show that the fin tip plays a vital role for promoting the higher heat transfer rate.

“…Their investigation presented that the Nusselt number is enhanced more than four times as a result of augmentation of triangular fins. Iqbal et al [16] studied the parabolic FDP and suggested many optimal configurations of FDP based on the Nusselt number. Ishaq et al [17] studied the heat transfer enhancement in FDP with different fin heights of triangular shape.…”

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]
