“…In particular, R. Song [70] studied the correlation of heat transfer and flow friction characteristics of fins for hydrodynamics, stressing the importance of developing generally accurate formulas for optimization, adopting Fluent for numerical simulation. They obtained good agreements between numerical simulation and the Manglik & Bergles correlation [37], which validates the reliability of the numerical simulation method…”

This paper presents a detailed review of the research carried out for the design of flat fin heat exchangers is using theoretical, experimental, and computational fluid dynamics (CFD) methods. The scope and limitations of several studies are presented, as well as the critical point of view of the authors in the selection of optimal methods in the thermo-hydraulic design of each equipment. Fin heat exchangers optimization is done using different approaches. The theoretical model assumes considerations that do not fully replicate the phenomenon, the experimental method provides real parameters for the design and implies high costs, and finally, computational fluid dynamics predicts the behaviors of thermal and hydraulic machine flows, in addition to recreating the phenomena almost exactly and complement the theoretical and experimental methods. With this review, it can be verified that the methods complement each other, thus achieving greater profitability at the industrial level, greater robustness in the design, and facilitating the study of behavior from a thermo-hydraulic approach.

“…The velocity distribution in the cross section of the tube with viscous flow is not parabolic, due to the change of the viscosity with the temperature in the straightaway section. The velocity distribution is dependent if the fluid be heated or cooled (see Figure 1) [2]. For a same mean temperature in the cross section, the temperature for the fluid near of the wall is major when he gets heat, that when he gets cold.…”

In this paper is presented a new procedure for the calculation of the heat transfer in vertical and inclines tubes, with presence of viscous-gravitational flow. Three models, one for inclines tubes and two for vertical tubes with presence of downward and upward flow were developed. The first model was development for coincident directions and 12 different fluids, included water and organic liquids, shows a correlation adjustment with a mean error of 12.75% in 81.51 % of the available experimental data in the interval of validity 7.5 × 10 5 ≤ Ra < 2.75 × 10 11 and 0.9 < Pr ≤ 3.5 × 10 4 . The second model was development for not coincident directions and 10 different fluids, included water and organic liquids, shows a correlation adjustment with a mean error of 13.04% in 83.09 % of the available experimental data in the interval of validity 7.6 × 10 5 ≤ Ra < 1.45 × 10 11 and 0.8 < Pr ≤ 3.9 × 10 4 . The third model was development for inclined tubes, it is valid for 10 different fluids included water and organic liquids, shows a correlation adjustment with a mean error of 16.12%, in 81.08% of the available experimental data in the interval of validity 7.9 × 10 5 ≤ Ra < 6.98 × 10 10 , 0.9 < Pr ≤ 2.1 × 10 4 and angle of inclination with respect to horizontal line 1 °≤ θ ≤ 88 °. The objective of this paper is to make a procedure of analysis that enables considering the influence of the gravitational effects in the laminar flow regimen and to decrease the average uncertainty of the models and that additionally has a larger range of applicability.

“…In recent years, more and more researchers considered the fractal parameters to describe the heterogeneous, multi-scale and self-similar of fracture system. [23][24][25][26][27][28][29][30][31] Chang and Yortsos 28 presented a formulation for using fractal geometry objects to represent fracture system, analyzed the system's pressure-transient response, and showed that fractal dual-porosity systems can be used to identify and model fractured reservoirs. Cossio 32 applied the fractal permeability and fractal porosity in a trilinear flow model.…”

Most models for multiple fractured horizontal wells (MFHWs) in tight oil reservoirs (TORs) are based on classical simplified dual-porosity model that ignores the influence of imbibition, while the distribution of fracture system is heterogeneous, multi-scale and self-similar, which can be described by fractal dual-porosity model on fractal theory, and imbibition production is the important part of fracture system production. In this paper, a multi-linear fractal model (MFM) considering imbibition for MFHWs in TORs was established based on fractal theory and semi-analytical method. In this model, fractal theory was used to describe the heterogeneous, complex fracture network, and imbibition was considered by analogy of fluid crossflow law in fractured-porous dual media. And the approximate analytic solution was given by using the Laplace transformation and iteration method. The pressure responses in the domain of real time were obtained with Stehfest numerical inversion algorithms. The pressure transient and production rate were used to analyze, and sensitivity analysis of some related parameters were discussed. The results show that the fluid flow in MFHWs can be divided into nine main flow periods by analysis of type curves, and the fractal parameters of fracture system have great effect on the middle and later periods and imbibition influences the period of crossflow.
