With the beginning of the industrial revolution in the eighteenth century, ICE, refrigeration equipment and power stations developed. All of the above devices use TBHE. The important thing is the recent increase in energy demand, which led researchers to find optimal solutions to save the largest amount of energy. The objective of this review can be summarized in the research published in the field of TBHE of all kinds. In order to improve the performance of the TBHE, two basic conditions must be met, the first is to increase the CHTC, and the second is to reduce the PD across the HE. In order to reach this goal, many influential variables must be studied, including pipe diameters and shapes, vertical and horizontal distances, fins shape, and installation method. In addition to the arrangement of the tubes through the TBHE. It was in the form of IL or staggered, the type of flow that was stratified or turbulent. The most important variables affecting on the performance of HEs can be summarized in general. The shape of the pipes had a greater urgency in the process, as the flat pipes had better performance than the circular TBHE. Both the PD and the CHTC are a function of the Reynolds number, as both increase with the increase in the Reynolds number. Therefore, studies in this field must be intensified to obtain the optimal design TBHE, taking into account all the above variables.

“…A study concerning with complex flows and heat transfer of the laminar flow regime around a single row of tubes in a channel is given by Cho J. and Son C. (2009). The time-dependent numerical approach predicted the generation and evolution of vortical structures, wakes interactions, and their effects on the drag, lift and heat transfer of the range of Reynolds number 20 to 180.…”

One row of heated elliptical cylinder with aspect ratio 0.6 and 0.8 are studied to know the forced heat transfer performance. The transversal distance between the cylinders are changed and the heat transfer is observed. Numerical observation of the study is done by using finite volume method to solve the momentum equations in two dimension domains. The pressure term instead of velocity is obtained by measurement in a subsonic wind tunnel and then it is injected into the momentum equation. The results of the hydrodynamic calculation are then injected into the energy equation which is solved by the over relaxation iteration method. The results of numerical calculation show that the drag coefficient due to flow friction changes with the distance between two elliptic cylinders. At certain distance, the cylinders behave as single cylinder and no influence each other. The Heat transfer performance for small distance between the cylinders has lower values compared to larger distance. It increases with the increase of distances and at a certain distance, there is no more increases. It means that the heat transfer tends to a constant value. Heat transfer ability is depending on the aspect ratio of elliptic cylinder.

“…Zdravistch et al [20] used a finite volume technique and presented results for two pitch-to-diameter ratios of 1.5 and 2.0 with various Reynolds numbers based on the velocity of approach from 54 to 120 at a fixed Pr number of 0.7. It is boosted using the finite volume technique in a 2D by Cho and Son [21], and 3D by Tsai and Sheu [22]. Beale and Spalding [23] numerically evaluated the heat transfer and fluid flow in a tube bundle.…”

This paper presents variation of overall dimensionless heat transfer rate against dimensionless tubes spacing, fins density, Reynolds number for in-line configuration. Influence of Reynolds number on the predicted and experimental results of dimensionless pumping power minimization for with respect to the dimensionless fins density for several tube-to-tube spacing also investigated. The experiments were conducted at a flat tube in the flow direction, and Reynolds number based on the hydraulic diameter (ReDh) was considered. The dimensionless overall heat transfer rate is always increases with an increase of the Reynolds number. The dimensionless fins spacing effect on the dimensionless overall heat transfer rate increase is noticeable at high Reynolds numbers. The dimensionless pumping power increases with increasing response Reynolds numbers for dimensionless tubes spacing and dimensionless fins density. The dimensionless pumping power decreased with increase of dimensionless fin density.
