Manufacturers looking to improve the fuel economy of off-road equipment should take a lesson from the automotive industry. Straight-grade engine oils have not been approved for use in passenger cars ...

Dilatants are a class of non-Newtonian fluids characterized by their ability to transition from a fluid state to a near-solid state under shear stress due to a high concentration of solid particles ...

Hydraulic oil ranks high among fluids with multi-function capability. True, for sheer utility, it can’t match olive oil, which through the centuries has been used as food, lubricant, fuel, medicine, ...

Realistic prediction of the characteristics of the elastohydrodynamic lubrication (EHL) contact requires consideration of the appropriate constitutive equation for the lubricant. In many applications, ...

Researchers are using ultrasonic waves to manipulate the viscosity of shear-thickening materials, turning solids to slush -- and back again. Researchers are using ultrasonic waves to manipulate the ...

An international research team is attracting the attention of experts in the field with computational results on the behavior of ring polymers under shear forces: They showed that for the simplest ...

The next generation of protective equipment is looking a lot less bulky and a lot more fluid. Shear thickening fluids (STFs) are novel field-responsive materials that can be engineered to be useful ...

The effect of fluid motion on the excitation of bioluminescence was examined for cultured dinoflagellates and plankton samples subjected to steady state laminar shear associated with simple Couette ...
