Solar Water Desalination 2-D (Species Transport) , ANSYS Fluent CFD Simulation Training

The present study investigates the performance of a solar-still thermal desalination unit by ANSYS Fluent software. The current model consists of a small chamber with a sloping glass surface at the top. The resulting vapor impacts the cold glass surface and undergoes a distillation process. Pure water from hot vapor distillation moves down the slope of the glass plate and discharges as pure water.

One of the thermal methods of water desalination is using solar desalination units. In solar water desalination, solar energy is used as a heat source and causes the evaporation process. In the functional mechanism of this type of desalination, surface evaporation occurs by solar energy. The produced vapor collides with the cold surface of the glass and converts to pure water after distillation.

Desalination Methodology

The solar heat passes through the glass to the water’s surface in the enclosure and causes surface evaporation (applying a UDF for surface evaporation).

The Species Transport method is used. This method does not simulate saline water flow in the device. Unlike multiphase simulations with much heavier computations, this method assumes that there is a mixture of air and vapor inside the chamber interior.

The simulation focuses solely on the amount of vapor produced in the system. The present study aims to investigate the amount of vapor produced on the water surface and the cold surface of the sloping plate.

Also, the solver is Steady-State. The present 2-D model was designed by Design Modeler software. The geometry consists of a sloping glass surface at the top and a horizontal water plate at the bottom. A Structured mesh was performed using ANSYS Meshing software. The element number is 16,000.

Desalination Conclusion

This method assumes a mixture of air and vapor inside the chamber interior and does not simulate distilled water flow.

In fact, at the beginning of the simulation, the space inside the chamber is filled with air only; the bottom plane of the chamber is considered the surface of the water, and since the water evaporates on the surface, it is assumed that the surface consists of vapor.

It is also assumed that the sloping plate where the steam collides is composed only of vapor. So water and air mass fraction contours completely show the evaporation in the device.

    This CFD training product for solar water desalination appears fascinating. I was wondering, though, have any studies addressed potential solutions for increasing the efficiency of this desalination process?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      Absolutely! Various strategies can be employed to boost the performance of a solar still desalination system. This includes optimizing the chamber’s shape, improving the heat absorptivity of the water basin, using selective coatings on the glass cover, and incorporating phase change materials to store solar energy. Each technique would require specific modifications to the simulation setup, which can certainly make for an intriguing follow-up study.

    The description tells me how the process works but doesn’t mention temperatures. What temperatures are set for the vaporization process, and what surface temperature is considered for the condensation on the glass plate?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      The simulation setup for vaporization takes into account solar energy as the heat source. A UDF (User Defined Function) could potentially define the specific temperature at which water evaporates. As for the condensation on the glass plate, it typically represents a colder surface, but the exact temperatures could vary. The simulation results would indicate the temperature gradient necessary to achieve the distillation process. Since these specifics weren’t provided, I’d recommend revising the product documentation for detailed temperature parameters.

    What kind of simulation setup allows the solar water desalination study to avoid simulating saline water flow within the device?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      The Species Transport method is utilized in the solar water desalination study to avoid simulating saline water flow within the device. This method assumes that there is a mixture of air and vapor inside the device instead of tracking the separate phases of saline water and air.

  11. Avatar Of Gardner Gerlach

    Gardner Gerlach

    I’m fascinated by the Species Transport method used in the solar water desalination simulation. The efficiency of solar energy conversion seems crucial. Can you tell me how the evaporation rate varies with changes in solar energy intensity? Is there a direct correlation model included in the software for this purpose?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      In the solar water desalination simulation using ANSYS Fluent, the evaporation rate is directly influenced by the intensity of solar energy. To model this, a User-Defined Function (UDF) can be implemented to define the relationship between the evaporation rate and solar energy intensity, allowing you to take into account any direct correlation. This UDF will specify the heat transfer and phase change at the water surface to simulate evaporation.

    Does this solar desalination simulation account for the temperature variations throughout the day?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      No, the described simulation assumes a steady-state solver, which means it does not account for transient thermal effects like temperature variations throughout the day. It simplifies the process by focusing on a single state, rather than changing conditions over time.

    I’m happy with the training progress! The step-by-step approach really helped me understand solar water desalination. Just curious, is the slope of the glass surface critical for the process? And, how does changing the angle affect the distillation efficiency?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      Yes, the slope of the glass surface is indeed crucial for the solar water desalination process. It influences the cooling rate of the vapor and facilitates the condensation and collection of distilled water. Adjusting the angle of the glass surface impacts how efficiently the system can condense vapor into water and how gravitational forces assist in collecting the pure water. Different angles could be simulated to optimize the process for maximum efficiency.
