The study of non-Newtonian fluids has sparked great interest in science and engineering. These fluids exhibit exceptional behavior in contrast to traditional Newtonian fluids, defying the laws of viscosity that we have known. In this sense, one of the most fascinating and studied non-Newtonian liquids is the so-called "non-Newtonian liquid", whose consistency changes depending on the force exerted on it. In this white paper, we will explore how to create this non-Newtonian liquid and analyze its behavior and applications from a neutral approach.

1. Introduction to the non-Newtonian liquid and its properties

A non-Newtonian liquid is a substance whose viscosity and flow do not follow Newton's law of viscosity. Unlike Newtonian liquids, such as water and oil, non-Newtonian liquids exhibit peculiar behaviors when subjected to external forces. These liquids can change their viscosity in response to stress or shear, resulting in fascinating properties useful in various applications.

One of the most common properties of non-Newtonian liquids is pseudoplasty, which is the decrease in viscosity when the applied force is increased. This means that, with greater stress or shear, the non-Newtonian liquid becomes more fluid and less resistant. A common example of a non-Newtonian liquid is a mixture of cornstarch and water, known as "cornstarch sludge." When pressure is applied to this liquid, such as by squeezing it forcefully or hitting it, it becomes solid and behaves like a kind of solid mass.

Another interesting property of non-Newtonian liquids is thixotropy, which is the ability to return to its original state after having been subjected to efforts. Some non-Newtonian liquids, such as certain types of paint or adhesives, can gel when at rest and flow again when agitated or subjected to shear force. This property is especially useful in industrial and medical applications, where it is required to control the viscosity of materials at different stages of the process.

In summary, non-Newtonian liquids are substances whose viscosity and flow do not follow Newton's law of viscosity. These liquids have peculiar properties, such as pseudoplasty and thixotropy, that make them unique and versatile in various applications. Understanding and taking advantage of these properties is essential for their use in fields such as industry, medicine and scientific research. [].

2. What is non-Newtonian liquid and how does it work?

Non-Newtonian liquid is a type of fluid that does not follow the laws of viscosity established by Newton. Unlike traditional liquids, its viscosity and fluidity change in response to the pressure or force applied to it. This unusual behavior is due to the presence of particles suspended in the liquid, such as corn starch or wheat flour.

When the non-Newtonian liquid is at rest, it acts like a normal liquid, but when a force is applied to it, it becomes more viscous and can even behave like a solid. For example, by dipping your hand in a mixture of cornstarch and water, the mixture will become hard and resistant, allowing the hand to be submerged without sinking into it. However, if pressure is applied to the mixture, such as hitting it, it will behave like a liquid and allow the hand to sink.

This surprising behavior of the non-Newtonian liquid is due to the way the suspended particles interact with each other. When a force is applied, the particles clump together and form a kind of solid structure that makes it difficult for the liquid to flow. On the other hand, when no force is applied, the particles disperse and allow the liquid to flow freely.

The non-Newtonian liquid has several practical applications, such as in the manufacture of knockout armor, anti-slip coatings and impact-resistant packaging fillers. In addition, it is also used in games and recreational activities, such as the popular experiments of mixing corn starch and water. to create a viscous and fun liquid with which you can make different shapes and manipulations.

3. Types of non-Newtonian liquids and their characteristics

There are different types of non-Newtonian liquids, which have different characteristics than traditional Newtonian liquids. One of them is the dilatant liquid, which increases its viscosity when subjected to shear stress. This means that when force is applied or stirred quickly, the dilatant liquid becomes thicker and takes on a solid-like consistency. Examples Dilatant liquids are a mixture of flour and water, or a solution of cornstarch and water.

On the other hand, there are also pseudoplastic liquids, which decrease their viscosity when a shear force is applied to them. These liquids become thinner and thinner when subjected to agitated motion or force, such as ketchup or nail polish. As force is applied, these substances become easier to pour or spread, due to their change in viscosity. This is because the liquid particles align and separate from each other, allowing it to flow more easily.

Finally, viscoelastic liquids have characteristics of both solids and liquids. These materials have the ability to deform and flow like a liquid when a force is applied, but they also have elasticity and can recover their original shape once the force ceases. Silicone and silica gel are common examples of viscoelastic liquids. These liquids are very versatile and are used in various applications, such as in the medical industry or in the manufacturing of electronic products.

4. The importance of the balance between viscosity and applied force

To understand the relevance of the balance between viscosity and applied force in a process, it is essential to understand how these two factors they interact with each other. The viscosity of a fluid refers to its internal resistance to flow, while the applied force is the energy used to move or alter said fluid. In many cases, it is necessary to strike the right balance between the two to ensure the efficiency and success of the process.

If the viscosity of a fluid is too high, it can be difficult to move or alter with applied force, which can lead to a number of complications. On the other hand, if the viscosity is too low, the flow can become unstable and difficult to control. To find the right balance, it is essential to consider fluid properties, working conditions, and process objectives.

There are several methods and tools that can be used to evaluate and control the balance between viscosity and applied force. Some of these tools include viscometers, which measure the viscosity of a fluid, and equipment for measuring applied force. In addition, it is important to perform tests and experiments to determine how the behavior of the fluid varies with different levels of applied force and viscosity. This will allow you to adjust and optimize the process to achieve the desired results.
