“…The transient temperature compared with the experimental work of Zhang et al 34 beginning of the process, therefore, due to the shape of the cross-section and the greater effect of convective heat transfer at the same time, this cross-sectional configuration has a higher liquid fraction compared with the inverted triangular cross-section configuration.…”

“…Therefore, based on the good adoption of the numerical results of the present simulation by the results of Elmirah et al 20 and Kumar and Krishna, 33 the present study is validated. Also, to further ensure the validity of the solution method, the results of numerical simulation have been compared with the experimental investigation of Zhang et al, 34 which according to Figure 7, the increasing trend of temperature is the same in both methods at a specific point of the PCM. The error is small until the middle of the melting process and after that the error increases at some times so that the maximum error of the numerical analysis is 10.4% compared with the experimental analysis.…”

By considering the ability of phase change materials (PCMs) in the storage of energy, the melting of four types PCMs including RT22, RT26, RT35, and RT41 in a heat exchanger is examined in this research. The impact of various shell cross‐sectional configurations on the complete melting time of materials, temperature changes, and liquid fraction throughout the melting process are presented. It is assumed that the main heat transfer fluid in the tube is non‐Newtonian and the tube is filled with a porous medium. The enthalpy porosity manner is applied for simulating the process of phase change and the heat natural convection and conduction cases are discussed. On the basis of the obtained results, the decrease in complete melting time is about 20% compared with the absence of a porous medium in the circular cross‐section configuration. The shell configuration has a noticeable impact on the reduction of the required time for melting. In the square cross‐section configuration, RT22 has the lowest melting time, as well as RT41 has the longest melting time in the inverted triangular cross‐section configuration in which the maximum time difference for RT22 is about 77% less. So, the best cross‐section for the shortest complete melting time is square.

Aiming at the thermodynamic problem of heat transfer fin in heat storage system, the solidification and melting model and thermodynamic conventional model are established by using simulation software, thermodynamic image processing and other methods. MATLABAB, COMSOL and other software are used to program the optimal rectangular fin spacing Angle and the optimal heat exchange fin structure. Firstly, based on the reason that the simulation software can simulate the heat transfer process of phase change material (PCM) in the actual process to the greatest extent, the plane modeling and thermodynamic equation method are used to analyze the distance Angle of the rectangular fin, and the melting solidification model is established, and the optimal solution is obtained. Finally, combined with the analytic hierarchy model and TOPSIS method, the triangular fin structure and rectangular fin structure were compared from three levels, namely, the heat sink area, temperature rise time and PCM maintenance time of different shapes. And create a heat transfer rate of return to more favorably analyze the data and visually present the comparative results.
