Industrial applications use special kinds of liquids called non-Newtonian fluids. These fluids act differently under stress, which makes them very useful in many industries.

Unlike regular liquids (called Newtonian fluids) that have a constant thickness, non-Newtonian fluids can change their thickness based on how much force is applied to them. This ability can be tailored to meet specific needs in various manufacturing processes.

For example, in food processing, certain non-Newtonian fluids are helpful. Think about ketchup and sauces. When you shake or stir them, they become runnier, making it easier to pour. This makes them easier to handle and package during production.

In the cosmetics industry, non-Newtonian fluids are also used. They help create products that go on smoothly but stay stable in their containers.

In the construction industry, non-Newtonian fluids like cement slurries have a special property called thixotropy. This means they can flow when mixed but become stable when left alone. This is super important because it allows cement to be mixed and poured easily but keeps it in place as it hardens.

Another important use of non-Newtonian fluids is in biotechnology. These fluids can act like biological fluids, which helps scientists control important processes like giving medicine to patients and growing cells. Being able to adjust how these fluids flow can make these processes work better.

In summary, non-Newtonian fluids are vital in many areas because they can change and adapt to different situations. This adaptability helps improve efficiency and encourages new ideas in industrial applications. Understanding these fluids and how to use their unique properties can lead to advancements that help various engineering fields.
