“…In turn, Syed et al investigated the optimal configuration of the annulus with trapezoidal fins through the selection of the number of fins, fin height, fin thickness, and the radius ratio of the inner and outer tubes, using genetic algorithms and a trust region method. A similar investigation was also proposed by the same authors using parabolic fins and using a generalized optimization of the fin shape . Later, Han et al investigated the design of the outer surface corrugation of the inner tube using multiobjective optimization for the determination of optimal values of the pitch, height, and radius of the corrugation.…”

“…A similar investigation was also proposed by the same authors using parabolic fins 7 and using a generalized optimization of the fin shape. 8 Later, Han et al 9 investigated the design of the outer surface corrugation of the inner tube using multiobjective optimization for the determination of optimal values of the pitch, height, and radius of the corrugation. Their optimization was based on a response surface methodology (RSM) using simulation data generated through computational fluid dynamics (CFD).…”

This paper investigates the design optimization of double pipe heat exchanger using mathematical programming. The heat exchanger area is minimized and the thermo-fluid dynamic conditions are considered for the use of the right transport correlations, together with design specifications, such as, maximum pressure drops and minimum excess area. The modular nature of this kind of heat exchanger and the allocation of the streams (inside the inner tube or in the annulus) are also contemplated. Two mixed-integer nonlinear programming (MINLP) approaches are proposed. One approach relates the binary variables to the nonlinear constraints directly. In the second, the resulting nonlinearities involving binary variables are formally linearized, without loss of rigor (e.g., no use of truncated Taylor series). The proposed methodology can get better solutions than traditional trial and error procedures. The flexibility of the model is illustrated, together with a comparison between the performances of both MINLP formulations. Additionally, computational time and local optimality issues are discussed.

“…A large number of geometrical evolutions have been tested and studied as shown in the review given by Liu and Sakr [4]. Among the various examples of those enhanced geometries that can be found in the literature, internal fins [5], elliptic shaped turbulators [6] or twisted tape inserts inside the tube flow [7] can be cited. A successful application of the twisted tape insert to non-newtonian fluid has been recently reported [8].…”

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.
