“…On each fin surface, a total of 48 drills with 10 mm diameter and 20 mm center-to-center distance were drilled in two rows i.e 24 holes in each row. The properties of stearic acid considered as; density = 1.08 kg/m 3 , thermal conductivity = 1.18 W/mK, specific heat =2.83 KJ/kgK [26,27]. At a distance of 100 mm from the entrance and exit of TTHX, eight thermocouples were inserted to measure the temperature of stearic acid.…”

The energy storage capacity of latent heat thermal energy storage systems is high therefore these systems are efficient among all other thermal heat storage. This study experimentally investigates the charging and solidification of stearic acid (C18H36O2) in the finned triplex pipe heat exchanger with holes on the fin surface. The melting and discharging of stearic acid are carried out at steady inlet heat transfer fluid (HTF) i.e., water temperature. This study also investigates the result of the change in HTF flow rate on solidification and melting of phase change material. Finally, the study focuses on the comparison of average effectiveness for finned triplex tube heat exchanger and finned triplex tube with cylindrical holes on fin surface with rates of 0.33 and 0.43 Kg/s. The results showed that the average effectiveness with a finned triplex tube with a perforated fin surface is 4% more than that of a finned triplex tube at 0.33 Kg/s whereas it is 5 % more at 0.43 Kg/s during the charging process. On the other side during discharging process average effectiveness is 14 % more at 0.33 Kg/s and 11 % at 0.43 Kg/s.

“…The approach ensured a comprehensive and objective evaluation of the available alternative materials, leading to a well-informed decision regarding the most suitable composite material for the intended application. Gadhave et al 70 conducted a study on the selection of phase change material using three MCDM methods and utilized AHP—entropy methods to determine the criteria weights. VIKOR, TOPSIS and EXPROM2 methods were used to rank the alternative materials.…”

A large number of materials and various criteria fashion material selection problems as complex multi-criteria decision-making (MCDM) problems. This paper proposes a new decision-making method called the simple ranking process (SRP) to solve complex material selection problems. The accuracy of the criteria weights has a direct impact on the outcomes of the new method. In contrast to current MCDM methods, the normalization step has been eliminated from the SRP method as a potential source of producing incorrect results. The application of the method is appropriate for situations with high levels of complexity in material selection because it only considers the ranks of alternatives in each criterion. The first scenario of vital-immaterial mediocre method (VIMM) is used as a tool to derive criteria weights based on expert assessment. The result of SRP is compared with a number of MCDM methods. In order to evaluate the findings of analytical comparison, a novel statistical measure known as compromise decision index (CDI) is proposed in this paper. CDI revealed that the MCDM methods’ outputs for solving the material selection could not be theoretically proven and requires to be evaluated through practice. As a result, the dependency analysis-an additional innovative statistical measure is introduced to demonstrate the reliability of MCDM methods by assessing its dependency on criteria weights. The findings demonstrated that SRP is extremely reliant on criteria weights and its reliability rises with the number of criteria, making it a perfect tool for solving challenging MCDM problems.

“…However, different physical, chemical, and economic properties impact the selection, and, in some cases, these properties may conflict with each other when looking for selection criteria that seek the best results for each of them. No PCM contains all of the desired properties [21]; nonetheless, the selection during the design process can consider multiple criteria, even in conflict, through the application of multi-criteria decision-making methods (MCDM) [45].…”

“…In this step, VIKOR (Vise Kriterijumska Optimizacija Kompromisno Resenje) [45] and COPRAS (complex proportional assessment) [46] methods were applied for new PCM selection considering the properties identified in Table 3 as criteria for selection. The entropy method was used to determine the weights of criteria importance.…”

In recent years, phase change materials (PCMs) have been presented as a suitable alternative for thermal energy storage (TES) systems for solar water heater (SWH) applications. However, PCMs’ low thermal conductivity and the high dependence on external conditions are the main challenges during the design of TES systems with PCMs. Design actions to improve the performance of the TES systems are crucial to achieve the necessary stored/released thermal energy and guarantee the all-day operation of SWHs under specific system requirements. In this study, a TES with PCM in the configuration of a heat exchanger was redesigned, focused on achieving two main targets: an outlet water temperature over 43 °C during discharging time (15 h) and efficiency over 60% to supply the hot water demand of two families (400 L). A four-step redesign methodology was proposed and implemented through numerical simulations to address this aim. It was concluded that the type, encapsulation shape, and amount of PCM slightly impacted the system’s performance; however, selecting a suitable sensible heat storage material had the highest impact on meeting the system’s targets. The redesigned TES reached 15 operating hours with a minimum outlet water temperature of 45.30 °C and efficiency of 76.08%.
