The melting of paraffin in thermal storage tube-and-shell and combine-and-shell models was conducted with the numerical research aim of decreasing the charge time through changing the shape of the tube into combining form. The results discussed are temperature contour, liquid-solid interface contour, temperature distribution, liquid fraction, and the average Nusselt number. The results show that the charge time in the tube-and-shell model is 2000 s, while the combine-and-shell model is 1200 s, meaning an overall decrease in charge time in the combine-and-shell model by 40% when compared to that of the tube-and-shell model.

“…It was found that the melting time can be reduced by 19.9%, 26.9%, and 30.7% for the three tubes, respectively. Liu et al 16 numerically investigated the heat transfer enhancement technique using metal foam in a shell-and-tube system. In their model, appropriate source terms were added to the momentum equations to model the pressure drop caused by the presence of solid PCM and porous media.…”

“…The PCM occupies the space between the tube and the shell, and the heat is transferred from heat transfer fluid (HTF) which is circulated through the tube. 10 The main objectives of the researches on the shelland-tube system are to provide the guidelines for system optimization, [11][12][13][14] improve the total TES performance, 15,16 and analyze the parametric effects on the system. [17][18][19][20] Trp 11 numerically investigated the transient forced convective heat transfer between the tube wall and the HTF with moderate Prandtl numbers.…”

A thermal energy storage system using U-tube heat exchanger is proposed and compared with the system using singletube heat exchanger. Based on the enthalpy-porosity method, three-dimensional numerical models using computational fluid dynamics approach are developed to simulate the dynamic melting of phase change material in the two systems. Variable specific heat technique and combined conduction-convection heat transfer models are applied to achieve precise simulation. The model is first validated using published data, and then, the heat flux across the tube is used to evaluate the heat transfer performance of the two systems. Moreover, parametric studies are performed to analyze the effect of heat transfer fluid flow rate on the U-tube system by six different cases. The results show that during the melting of phase change material, vertical temperature stratification occurs in both systems as a result of the intensified natural convection. The results also demonstrate that the U-tube system has better heat transfer performance than the singletube system which has the same heat transfer area and boundary conditions, reducing the total charging time by 25%. Increasing the heat transfer fluid flow rate greatly enhances the heat transfer performance for the U-tube system, but further enhancement is limited by the fixed heat transfer area. This study provides an effective method to investigate the thermal behavior of thermal energy storage using phase change materials, and the results can be helpful in optimizing the future thermal energy storage design and practical applications.

“…This sort of media is mainly formed from multi-struts interconnected to each other at joint nodes to shape pores and cells (see the SEM image in Figure 1) (Liu et al [1]). They offer very high porosity (ε ≥ 0.89), light weight, high rigidity and strength, and a large surface area, which make them able to recycle energy efficiently.…”

This chapter is aimed as a concise review, but well-focused on the potentials of what is known as "High-porosity metal foams," and hence, the practical applications where such promising media have been/can be employed successfully, particularly in the field of managing, recovering, dissipating, or enhancing heat transfer. Furthermore, an extensive comparison is conducted between the formulations presented so far for the geometrical and thermal characteristics concerning the heat and fluid flow in opencell metal foams.
