(PhysOrg.com) -- Some scientists call the cosmological constant the "worst prediction of physics." And when today’s theories give an estimated value that is about 120 orders of magnitude larger than the measured value, ...
Getting two fluids to mix in small or confined spaces is a big problem in many industries where, for instance, the introduction of one fluid can help extract another — like water pumped underground can release oil trapped ...
Many engineering disciplines rely on supercomputers to simulate complicated physical phenomena — how cracks form in building materials, for instance, or fluids flow through irregular channels. Now, researchers in MIT’s ...
(PhysOrg.com) -- Engineering students at UC San Diego are studying the fluid dynamics of water in order to build a more comfortable and sanitary urine collection device for space travel.
Many medical devices for treating heart failure generate nonphysiological shear flow. This can trigger the destruction of red blood cells after implantation of ventricular assist devices (VADs), artificial heart valves, vascular ...
A new study from the University of Central Florida suggests that masks and a good ventilation system are more important than social distancing for reducing the airborne spread of COVID-19 in classrooms.
When Yu "Alex" Liang started graduate school at The University of Texas at Austin, he was tasked with running a straight-forward experiment to collect data on a well-understood phenomenon in fluid mechanics: how density differences ...
Whether a fluid is flowing through household plumbing or industrial oil and gas pipelines, when it runs slowly its flow is smooth, but when it runs quickly its flow is more chaotic.
Rhythmic patterns and precise motions—these are key elements of proper swimming. Olympians demonstrate repeated patterns of breathing, with synchronized head, leg and arm movements, enthralling spectators and provoking ...
One of the most promising approaches to curbing the flow of human-made greenhouse gases into the atmosphere is to capture these gases at major sources, such as fossil-fuel-burning power plants, and then inject them into deep, ...
