Fluid Flow Around a Wavy Tape in a Tube CFD Simulation

Problem Description of Fluid Flow Around a Way Tape

The present study investigates the fluid flow passing through a circular cross-section tube, using a wavy tape as a barrier. 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.
