Fluid Flow Around a Wavy Tape in a Tube, ANSYS Fluent CFD Simulation Training

The present study investigates the fluid flow passing through a circular cross-section tube, using a wavy tape as a barrier by ANSYS Fluent software. This waveform acts as a thermal insulator. The purpose of the present study is to investigate the heat transfer in a tube.

Assumptions for fluid flow around wavy tape CFD simulation

To simulate the present problem, several assumptions are considered:

The simulation is Steady-State and the solver is Pressure-Based. Also, the gravity effect is ignored

Geometry & Mesh

The present 3-D model was designed by Design Modeler software. The geometry of the model is a circular cross-section tube having barriers in the form of a wavy bar. Due to the symmetry of the model, the desired geometry is designed as a semi-cylinder. The unstructured mesh was done using ANSYS Meshing software. The element number is equal to 653307.

    What are the boundary conditions set for this simulation?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      The boundary conditions include the velocity inlet and pressure outlet. These are set based on the specifics of the tube design and the operating conditions.

    What are the main factors affecting the heat transfer performance of a tube with a wavy tape?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      The main factors include the design of the tape (e.g., wave amplitude and frequency), the properties of the fluid (e.g., flow rate, temperature, and thermal properties), and the operating conditions.

    Great results! I was impressed by the details in the 3D and 2D contours. Can you share more about how the presence of the wavy tape influenced heat transfer in the tube?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      We’re glad you liked the simulation results! The wavy tape creates turbulence within the flow, which enhances mixing and consequently increases the heat transfer rate within the tube. The surface texture of the wavy tape increases the surface area for heat exchange, contributing to a more efficient transfer of heat from the tape to the fluid or vice versa.

    How does the wavy tape enhance heat transfer in the tube?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      The wavy tape disrupts the flow, creating turbulence and increasing the convective heat transfer. It also increases the contact surface area between the fluid and the tube, which further enhances heat transfer.

    Even though the inlet velocity magnitude of water is low ( 0.0110334 m/s), doesn’t the wavy tape inside the pipe cause turbulent flow?

  6. Avatar Of Celine Schulist

    Does this simulation also take into account any radiative heat transfer or is it purely conductive and convective heat transfer that’s observed?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      In this provided case of simulation, heat transfer is handled purely through conductive and convective means. The Radiative heat transfer effect has not been included in the set of assumptions for this particular study.

    Splendid work on this CFD simulation! The wavy tape as a thermal insulator in a circular tube seems like a clever idea. The visual results demonstrating pressure and temperature variations suggest a profound understanding of fluid dynamics. The thorough approach from assumptions to solving with ANSYS Fluent shows significant expertise. Great job on the utilization of the Laminar model and the detailed boundary conditions application. It’s always exciting to see theory applied effectively in simulations like this.
