Enhanced fuel cell performance with optimized flows

Fuel cells convert the chemical energy in fuels (hydrogen and hydrocarbons such as methane, butane, gasoline or diesel) into electrical energy to power devices. EU researchers developed a simplified computational model simulating ...

Mathematicians model heat flow in human tears

Mathematicians from the University of Delaware have created a new model of the fluid dynamics and heat flow in human tears. When people blink their eyes, a thin liquid film is spread across the surface of the eye.

Microfluidics: Creating chaos

A quiet revolution is taking place in the fields of biology and chemistry. Microfluidic devices, which allow fluid manipulation in micro-scale channels, are slowly but surely finding their place on the lab bench. A new microfluidic ...

Pressurized vascular systems for self-healing materials

Artificial microvascular systems for self-repair of materials damage, such as cracks in a coating applied to a building or bridge, have relied on capillary force for transport of the healing agents. Now, researchers at the ...

Effortless sailing with fluid flow cloak

Duke engineers have already shown that they can "cloak" light and sound, making objects invisible -- now, they have demonstrated the theoretical ability to significantly increase the efficiency of ships by tricking the surrounding ...
