Hele-Shaw flow
Have you ever played with soap bubbles? Like blowing bubbles using a bubble wand? You might have noticed that the soap solution usually spreads out evenly inside the bubble wand, forming a thin film that starts to bulge out as you blow air into it.
This same principle of thin films spreading out evenly is also seen in a scientific experiment called Hele-Shaw flow.
The Hele-Shaw flow is a way of studying how fluids (like water) move through very thin spaces between two flat plates, which are kept fixed at a distance from each other. This space between the plates is so thin that the fluid inside it can be thought of as a "film" rather than a "flow."
To visualize this better, imagine two plates stacked on top of each other, like two slices of bread. In between the plates, you pour some water or any other fluid. The plates are so close to each other that the fluid inside is almost flat, like a pancake.
Now, if you push some more fluid into this tiny space between the plates, the fluid will spread out evenly and start bulging upwards, just like the soap bubble.
Scientists use the Hele-Shaw flow to study how different fluids behave, how they move through narrow spaces, and how they interact with each other. This experiment has helped in understanding various physical and biological phenomena, from the formation of ocean waves to the growth of cancer cells.
So, in short, the Hele-Shaw flow is a scientific experiment in which fluids are made to flow through a very narrow space between two flat plates, helping scientists study how fluids behave in different conditions.
