Description
Shell and Tube Heat Exchanger, PCM Thermal Storage System, Paper Numerical Validation, CFD Simulation by ANSYS Fluent
The problem simulates a phase change material solidification and melting inside a shell and tube heat exchanger using ANSYS Fluent software.
Numerical simulation has been performed based on the reference article [Experimental and computational evolution of a shell and tube heat exchanger as a PCM thermal storage system], and the results have been compared and validated with the results in the paper.
The results in the article are based on both experimental and numerical simulations. In general, phase change materials are materials with organic compounds that can absorb and store large amounts of latent thermal energy.
Thermal energy storage in these materials is achieved during the phase change process (solid phase to liquid or vice versa); So that when changing phase from solid to liquid, it absorbs heat from the surrounding environment (causes cooling of the environment), and when changing phase from liquid to solid, returns heat to the environment (causes heating of the environment).
The phase change material used in this simulation is RT50-type paraffin; Thus, it has a density equal to 820 kg.m-3 and a specific heat capacity equal to 2000 j/kg.K, and a thermal conductivity equal to 0.2 W/m.K.
Also, the viscosity of the phase change material depends on the temperature and is defined as a temperature-dependent exponential function in the form of a UDF function.
A shell and tube heat exchanger of copper, in which water flows with a mass flow equal to 0.008318 kg/s and a temperature equal to 343.15 K, enters the inner tube of the heat exchanger and inside the shell part of the heat exchanger is filled by the phase change material.
The present model is designed in three dimensions using Design Modeler software. The model is a shell and tube heat exchanger consisting of an internal tube. The thickness of the pipe’s inner wall is equal to 0.0025 m.
The pipe has a length of 1 m horizontally, and its inner and outer radii are 0.011 m and 0.0425 m, respectively. Due to the symmetrical structure of the pipe and to reduce the computational cost, a half geometry should be modeled.
We carry out the model’s meshing using ANSYS Meshing software, and the mesh type is structured. The element number is 169171.
CFD Methodology
In this simulation, the solidification and melting model is used to define the process of phase change material.
To define phase change materials, it should be noted that the maximum temperature at which the solid phase temperature is (solidus temperature) is 317.2 K, and the minimum temperature at which the liquid phase is dominant (liquidus temperature) is 327.3 K. And the pure solvent melting heat is defined as 170320 j/kg.
Shell and Tube Heat Exchanger Conclusion
At the end of the solution process, a graph of the temperature changes of the shell section containing the phase change material is obtained based on the time during a complete melting process.
This diagram of temperature changes is compared and validated with the diagram in Figure 8 of the reference article. The graph of the article includes the results of experimental work and numerical CFD simulation results.
The results show that the results of the current numerical simulation have an acceptable accuracy compared with the results of numerical and experimental work in the article. Also, two-dimensional and three-dimensional contours related to pressure, temperature, and liquid mass fraction have been obtained.

Mr. Dangelo Schuppe Sr. –
This product is impressive in detail and seems to provide a thorough analysis. Could you please clarify if the UDF for viscosity required any special adjustments or was it applied directly from the provided data in the research paper?
MR CFD Support –
In this simulation, the UDF for viscosity was crafted based on the temperature-dependent exponential function mentioned in the research paper. Any necessary adjustments or calibrations were made to ensure that the viscosity function accurately represents the behavior of the phase change material (PCM) under various temperature conditions within ANSYS Fluent.

Prof. Chadd Haley –
I was intrigued by the phase change material (PCM) used in this study— particularly RT50-type paraffin. Could you please expand on why RT50 paraffin is suitable for use in a shell and tube heat exchanger and its characteristics?
MR CFD Support –
RT50-type paraffin was chosen as the PCM for its suitable phase change temperature that aligns with the operational temperatures of many heat exchanger applications. It has a reliable phase change temperature range that ensures efficient absorption and storage of latent heat. Its characteristics, such as a density of 820 kg/m^3, specific heat capacity of 2000 J/kg.K, and thermal conductivity of 0.2 W/m.K make it effective in thermal energy storage during phase transitions. Additionally, its viscosity changes with temperature, and this temperature dependency can be accurately modeled in the simulation using a UDF function. This ensures a more precise evaluation of the material’s behavior at different temperatures.

Thank you for your kind words! Yes, implementing User-Defined Functions (UDF) can be complex, but they allow for a high level of customization and precise control in simulations where standard functions don’t suffice. In this case, the UDF function was crucial for accurately defining the temperature-dependent viscosity of the phase change material.

The paper validation aspect sounds interesting; can you elaborate on how you ensure that the numerical simulation results closely match with the experimental data in the reference article?
MR CFD Support –
In order to validate our numerical simulations against the experimental data in the reference article, we perform meticulous calibrations of our simulation parameters such as material properties, boundary conditions, and initial conditions to mirror the setups described in the article. We also utilize a fine and structured mesh to accurately capture gradients and phase change phenomena. Additionally, we rigorously compare the temperature changes, pressure distributions, and liquid mass fraction results from our simulation to those observed in both the numerical and experimental results presented in the article, ensuring alignment within an acceptable margin of error.
