Description

Description

The present problem simulates the performance of Phase Change Material (PCM) inside a shell and tube finned heat exchanger by ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.

Thermal energy storage in PCM is achieved during the process of the phase change (solid phase to liquid or vice versa); So that when the phase changes from solid to liquid, it absorbs heat from the environment, and when the phase changes from liquid to solid, it returns heat to the environment.

These phase-change materials have various melting or freezing temperatures and are used in cooling and heating systems. For example, these materials received ambient heat on a hot day as latent heat and melted, then returned to the environment by changing the phase and freezing process on a cold night.

The shell is designed as a cylindrical tank carrying phase change materials, and these PCMs are evenly distributed inside the tank. Since the PCMs of the present model are based on the phase change between the liquid and solid phases, the solidification and melting model has been used for the current simulation.

Because the simulation process is time-consuming, the simulation process is performed in a time interval of 880 s with a time step of the 1200s.

The current model is designed in three dimensions using Design Modeler software.

The meshing of the present model has been done using ANSYS Meshing software. The mesh type is unstructured, and the element number is 2989887.

PCM in Shell and Tube Methodology

In the current modeling, the phase change materials are paraffin material with a density equal to 750 kg.m-3, a specific heat capacity of 2000 j.kg-1.K-1, thermal conductivity equal to 0.2 W/m.K  and viscosity equal to 0.008 kg/m.s.

To define the Solidification & Melting model, the maximum temperature at which only the liquid phase prevails (T_solidus) is 314.15 K, the minimum temperature at which only the liquid phase is dominant (T_liquidus) is 317.15 K, and the latent heat of solvent melting at which is pure solvent melting heat is equivalent to 255000 j/kg.

Inside the tank, a 0.001 m thick copper pipe is routed through a winding path, which is responsible for heat transfer and, consequently, the occurrence of phase change of PCM.

The water flow with a mass flow of 1.4973 kg/s and a temperature of 325.15 K is considered inside this pipe. Also, cross-shaped fins inside the tank in the pipe path are made of copper.

PCM in Shell and TubeConclusion

At the end of the solution process, two-dimensional contours related to the temperature and mass fraction of the liquid are obtained. These contours are obtained during the last second of the simulation process, the 1200s.

The contours show well that with the passage of time and the melting of the PCM material, the heat transfer has taken place well, and the temperature in the center of the tubes has risen.

    What makes paraffin an effective choice for the PCM in this simulation compared to other materials?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      Paraffin is used as an effective phase change material in this simulation because of its suitable thermal properties. It has a relatively consistent density across phase changes, a high latent heat value, and a convenient phase change temperature, making it ideal for storing and releasing thermal energy in heat exchange systems.

    What benefits are there to using phase change material (PCM) in the shell and tube heat exchanger as opposed to not using it?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      Using Phase Change Material (PCM) in a shell and tube heat exchanger offers significant benefits, including enhanced thermal energy storage capacity, improved efficiency in heat exchange during the phase-change process, and the ability to release or absorb large amounts of thermal energy at a constant temperature. This can lead to better temperature control and system stability, reduced material costs, and increased longevity of the heating system.

    The methodology looks comprehensive. I was wondering how the solidification and melting process is visualized. Does the simulation offer a dynamic visualization of the phase change material changing states?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      Yes, the simulation provides dynamic visualization by generating contours for the temperature and the liquid mass fraction over time. These contours allow us to observe the heating and melting process within the PCM, showing how the heat transfer occurs and the temperature rises around the tubes as the simulation progresses to the final second due to the phase change from solid to liquid.

    This CFD simulation of the PCM in the shell and tube heat exchanger sounds very interesting. Could you explain how the efficiency of the PCM impacts the overall performance of the heat exchanger?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      In this particular simulation, the efficiency of the PCM relates to its thermal energy storage capability during the phase change process. A higher efficiency PCM would be able to absorb and release more heat, which impacts the overall heat transfer effectiveness of the heat exchanger. This could result in faster melting and solidification of the PCM, directly affecting the temperature regulation within the system.

      The use of Phase Change Materials (PCMs) in a shell and tube finned heat exchanger provides significant benefits for thermal energy storage. PCMs contribute to improved thermal efficiency through their heat absorption during melting and heat release during solidification. This leads to better regulation of system temperatures, increases the system’s ability to handle thermal loads, reduces the size and weight of the system by enhancing heat storage capacity, and contributes to energy savings by optimizing the use of available thermal energy.

    What happens during the simulation process if the mass flow of water flow changes?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      If the water flow’s mass flow changes, it will impact the heat transfer rate within the heat exchanger. A higher mass flow could remove heat faster, accelerating the phase change from solid to liquid of the PCM, whereas a lower mass flow could slow down the process. The simulation results such as the temperature distribution, velocity profile, and structure of the melted PCM would differentially manifest according to the alteration in the water flow’s mass flow rates.
