SAN ANTONIO — March 6, 2023 —A Southwest Research Institute team has developed a mechanical testing device to analyze fluids and lubricants formulated for electric vehicles. The team modified a ...

If there are no shear stresses present, there is no fluid deformation, and the behavior of a fluid is described by the bulk modulus relating the pressure and the compression strain. In the presence of ...

Automatic transmissions have evolved so dramatically over the past decades that today the same term covers fundamentally different mechanisms. A classical hydromechanical automatic transmission, a ...

Tests of a proposed friction-factor equation have shown it to be accurate for calculating pressure loss in turbulent flow for a pipeline transporting a non-Newtonian fluid, such as most crude oils and ...

The transition to electric vehicles (EVs) demands the development of specialized lubricants to meet their unique operating conditions. Unlike internal combustion engines, electric drivetrains feature ...

• Excessive seal friction wastes energy, accelerates wear, and can lead to premature failure. • Too little friction makes a seal prone to leak. • Pressure-activated hydraulic seals minimize both ...

Editor’s note: The Basics department this month is an excerpt from the ISA book Flow of Industrial Fluids – Theory and Equations by Raymond Mulley. Some material in this section may seem self-evident ...

For 15 years, scientists have been baffled by the mysterious way water flows through the tiny passages of carbon nanotubes — pipes with walls that can be just one atom thick. The streams have ...
