Textbook formulas for describing heat flow characteristics, crucial in many industries, are oversimplified, study shows. Whether it's water flowing across a condenser plate in an industrial plant, or ...

Blood may be thicker than water, but in a narrow enough tube, both liquids flow like treacle. This sluggish behaviour arises because, as you reduce the size of the channel, friction between the liquid ...

Every fluid -- from Earth's atmosphere to blood pumping through the human body -- has viscosity, a quantifiable characteristic describing how the fluid will deform when it encounters some other matter ...

Scientists at the Department of Applied Physics II of the University of Malaga have participated in the design of a new ...

If you’ve ever whacked the bottom of a ketchup bottle to get that tasty tomato goop flowing, you’ve put some serious physics to work. Ketchup is a non-Newtonian fluid. So are toothpaste, yogurt, ...

Under the right conditions, sand can flow. When heavier grains are placed atop lighter grains in a container, the less dense grains can burble upward like the blobs of a lava lamp, a study finds. The ...

A supercritical fluid refers to a state in which the temperature and pressure of a substance exceed its critical point, where ...

Water makes up around 60% of the human body. More than half of this water is inside the cells that make up organs and tissues, and much of the remaining water flows in the spaces between cells. MIT ...

A new artificial intelligence-based technique for measuring fluid flow around the brain’s blood vessels could have big implications for developing treatments for diseases such as Alzheimer’s. The ...
