What is COMSOL Multiphysics used for?
Engineers and scientists use the COMSOL Multiphysics® software to simulate designs, devices, and processes in all fields of engineering, manufacturing, and scientific research. COMSOL Multiphysics® is a simulation platform that provides fully coupled multiphysics and single-physics modeling capabilities.
What can non-Newtonian fluid be used for?
These include non-newtonian fluid friction reduction, oil-pipeline friction reduction, surfactant applications to large-scale heating and cooling systems, scale-up, and flow tracers. The use of high-polymer additives to enhance flow in petroleum pipe-lines has been a great commercial success.
Can Oobleck stop a bullet?
Fortunately, researchers have found liquids that work even better than water at stopping bullets. With shear-thickening fluids (affectionately known as oobleck), the bullet’s force is absorbed by the liquid, then dissipated outwards through the fluid medium.
Is Glue a non-Newtonian fluid?
There are two basic behaviors of non- Newtonian fluids. One type is termed shear thinning. Shear-thinning fluids decrease in viscosity when a shear stress is applied. Other shear-thinning fluids include margarine, gelatin, mayonnaise, honey, mustard, shaving cream, and Elmer’s glue.
How is ketchup a non-Newtonian fluid?
In non-Newtonian fluids, viscosity can change when under force to either more liquid or more solid. Ketchup, for example, becomes runnier when shaken and is thus a non-Newtonian fluid. The fluid can even exhibit time-dependent viscosity. Therefore, a constant coefficient of viscosity cannot be defined.
Is ketchup shear thinning?
Fortunately, ketchup also has an interesting shear thinning property. When an external force is applied in addition to gravity, the increased shear will result in decreasing the ketchup’s viscosity, allowing the product to flow more readily.
Can oobleck freeze?
Freezing the oobleck creates a solid. As the oobleck melts, the consistency keeps changing. This will keep your child interested for quite a while. Add toys to the oobleck and let your child have fun.
Is oobleck edible?
Luckily, the gooey substance is not toxic, but it probably won’t taste good since it’s just cornstarch and water. As one individual pointed out on Yahoo Answers, while eating oobleck may not be poisonous, it could potentially give someone pains in their stomach if large quantities are ingested.
