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.
CFD Simulation Procedure
Here is a summary of the steps to define and solve the problem in the table:
|Boundary conditions for fluid flow around wavy tape CFD simulation|
|0.0110334 m.s-1||velocity magnitude|
|0 Pa||gauge pressure|
|0 W.m-2||heat flux||wave wall|
|360 K||temperature||outer wall|
|second order upwind||pressure||Spatial discretization|
