Much of "microfluidics" is "millifluidics" because it handles fluids on the millilitre scale. Similarly, much of "nanofluidics" is "microfluidics" because it handles fluids on the microlitre scale. So we'll just use one word, microfluidics, to describe the whole world of making stuff flow down small, complex channels for various interesting applications.
The small selection of apps is intended as a first step towards a bigger collection. I'm happy to add anything that you think is relevant and which has a tractable, appable, theory. Just let me know.
- Contact Angles lets you explore the effects of roughness and "plain" contact angle on the actual contact angle
- Capillary Bubbles shows how easy it is to block a capillary with gas that comes out of solution at a higher temperature
- Capillary Flow explores what happens when you try to fill a rectangular capillary
- Capillary Fill Time shows that using a syringe to fill a capillary might not be as easy as you might think
- T-Mixer shows why we usually need more complicated mixers in our microfluidic devices.
