- •
The 3-D T-mixer aspect ratio has relevant effects on flow patterns and quality of mixing.
- •
Mixing increases drastically for Re up to 100 in the mixing channel in all designs formed by increasing the width of the channel while fixing its height.
- •
Non-stable flows that help on mixing are present with Re > 250 for some aspect ratios of mixing channel.
- •
In the Re range 50–700, the 3-D T-mixer presents better mixing performance than the typical T-mixer for all aspect ratios of mixing channel.
