Overview of Fluid Flow Around a Wavy Tape in a Tube CFD Simulation
Project Description
This study studies fluid flow through a circular tube including a wavy tape as a thermal insulating barrier using ANSYS Fluent. The research focuses on heat transfer analysis within the tube.
Assumptions
Using a pressure-based solver, the simulation is steady-state; gravitational influences are ignored.
Geometry & Mesh
Designed in Design Modeller, the 3D model has a semi-cylinder with wavy boundaries indicating the symmetrical tube. Using an unstructured mesh with 653,307 components, ANSYS Meshing performs meshing.
CFD Simulation Procedure
Models and Boundary Conditions
- Viscous Model: Laminar
- Energy Equation: Enabled
- Inlet: Velocity of 0.0110334 m/s, Temperature of 293.15 K
- Outlet: Pressure set to 0 Pa
- Wall: Wave wall with heat flux of 0 W/m², Outer wall temperature at 360 K
Solution Methods
- Pressure-velocity coupling using SIMPLE
- Second-order upwind discretization for pressure, momentum, and energy equations
Initialization
- Standard initialization with z-velocity set at -0.0110334 m/s, Temperature at 293.15 K
Results
The simulation produces 3D and 2D contours of pressure, temperature, and velocity as well as flow lines and velocity vectors in both 2D and 3D formats post-solution, therefore offering thorough knowledge of the fluid dynamics and heat transfer properties around the wavy tape.
