Channel flow simulation using CONVERGE CFD

CFD simulation was carried out on Channel flow using Converge package.

Converge case setup was done using Converge, and post processing was carried out both using converge and Paraview.

Following are the results:

1. Base grid: 2e-4m

Grid:

Velocity_visualization in Paraview:

Pressure visualization in Paraview

Velocity plotted in paraview using plot on line function at 0.08 position from origin in streamwise direction:

2. Base grid: 1.5e-4m

Grid visualization:

We can see this grid is finer as compared to 2e-4 grid.

Velocity plotted in paraview using plot on line function at 0.08 position from origin in streamwise direction for 1.5e-4m

For velocity in streamwise direction, we can see the number of steps are more as compared to 2e-4, because the grid is finer. Hence as the resolution increases, the results becomes more accurate reaching analytical solution of parabolic profile

3. Base grid: 1e-4m
