The present study investigates the fluid flow passing through a circular cross-section tube with a wavy tape inside it.

## 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.

1. Chauncey Reichert

What are the boundary conditions set for this simulation?

• 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.

2. Dr. Colin Pollich

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

• 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.

3. Aisha Anderson IV

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

• 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.

4. Margaret

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?

5. Dr. Lafayette Kuhn

I have a keen interest in a simulation that involves an alternate tape design. Is it possible for you to facilitate this?
