Shear Thinning? What’s That?

Shear thinning means that as you apply more force (shear) to glycerol, it becomes less viscous. It’s like a shy kid at a party – the more you push, the more it flows.

This behavior makes glycerol perfect for certain applications. For instance, in cosmetics, it helps creams and lotions spread smoothly without feeling sticky. In hydraulic fluids, it reduces friction and improves efficiency, making machines run smoother than a greased pig.

So next time you’re slathering on your favorite lotion or taking a sip of your favorite soda, remember that glycerol’s shear thinning superpower is working behind the scenes, making your life just a little bit easier and more enjoyable!

Shear Thickening: Viscosity with Attitude

Picture this: you’re stirring a thick, sticky batter, and suddenly, it transforms into an unyielding mass. That’s shear thickening in action! Shear thickening, or dilatant behavior, occurs when a fluid becomes more viscous as shear is applied to it. It’s the opposite of shear thinning, where fluids become less viscous with increased shear.

How Does It Work?

Imagine a crowd of people at a concert. When the crowd is calm, everyone can move around freely. But as the crowd becomes denser, people start to bump and slow each other down. In a similar way, when a shear thickening fluid is sheared, the molecules or particles in the fluid collide and their interactions become more entangled, leading to increased resistance to flow.

Real-World Examples

Shear thickening fluids have some surprising applications:

Cornstarch suspensions: Mix cornstarch with water, and you get a gooey mess that can act like a solid when you apply force to it. This is why kids love playing with cornstarch!
Body armor: Some bulletproof vests use shear thickening fluids to resist the impact of bullets. As the bullet passes through the fluid, it creates a shock wave that increases the fluid’s viscosity, slowing down the bullet.
Walking on water: Researchers have developed shear thickening fluids that allow people to walk on water for short distances. As the person’s foot presses against the fluid, it becomes more viscous, supporting their weight.

Shear thickening is a fascinating phenomenon that shows how fluids can behave in unexpected ways. From cornstarch suspensions to body armor, shear thickening fluids have a variety of applications that make them more than just liquids that flow.

Thixotropy: Fluids that exhibit time-dependent viscosity changes

Thixotropy: When Fluids Get a Little Timey-Wimey

Imagine a fluid that’s like your favorite yogurt. When you first open the container, it’s thick and gooey. But give it a good stir, and it suddenly becomes smooth and pourable. That’s thixotropy in action!

Thixotropic fluids have a curious property: their viscosity changes over time. When you leave them undisturbed, they become thicker. But when you apply force or stir them, they thin out. It’s like they have a memory of their past experiences.

Think of ketchup. When you first squeeze it out of the bottle, it’s thick and stubborn. But as you start to spread it on your burger, it becomes smooth and glides on effortlessly. That’s because the act of spreading is breaking down the thixotropic structure, making it easier to flow.

This unique behavior makes thixotropic fluids useful in a variety of applications. In paints, they prevent brush strokes from sagging. In cosmetics, they give products a creamy texture that glides on smoothly. And in industrial processes, they help control the flow of fluids through pipes and machinery.

So, the next time you reach for your favorite yogurt or spread some ketchup on your burger, remember the amazing science behind its flowy properties. It’s all thanks to the wonders of thixotropy!

Dilatancy: Fluids that increase in volume when sheared

Dilatancy: When Fluids Puff Up Like Popcorn

Hey there, fluid enthusiasts! Ever heard of a fluid that gets bigger when you shake it up? Sounds like magic, but it’s real! Welcome to the wacky world of dilatancy.

Dilatancy is a fascinating phenomenon where a fluid increases in volume when subjected to shear force. Think of it as the opposite of a sponge that compresses when you squeeze it. Instead, dilatan fluids expand, giving them unique and surprising properties.

One example of a dilatan fluid is a cornstarch and water mixture. If you pour it slowly, it behaves like a liquid. But give it a good shake, and boom! It instantly solidifies into a paste-like substance. That’s because the cornstarch particles pack together under shear, creating a larger volume.

Dilтанcy has some really cool applications too. For instance, it’s used in body armor to absorb impact. When a bullet strikes, the fluid inside the armor dilates, dissipating the impact energy. It’s also found in some toys, like the “Oobleck” slime, which can change from a liquid to a solid depending on the amount of force applied.

So, there you have it, dilatancy—the mind-boggling property where fluids puff up like popcorn. Just remember, if you ever find yourself dealing with a dilatan fluid, be prepared for some unexpected surprises!
