Physicists simulate engine oil behavior under extreme pressure
(PHYSorg.com Physics)

Researchers from the Moscow Institute of Physics and Technology (MIPT) and elsewhere have modeled the behavior of a widely used lubricant under extreme conditions. Their calculations on Russian supercomputers spare the costly experiments and predict how the viscosity of 2,2,4-trimethylhexane changes between the standard conditions and a pressure as high as 10,000 times that in your room. The findings, reported in Fluid Phase Equilibria, are key for the industrial applications of similar fluids in aircraft engines, as fuel additives and electrical insulators.
