Summary:

Studies on improving heat load of sliding -contact components system (piston set and cylinder liner) by applying nanofluids have been carried out. Numerical simulation was employed and the piston set-lubricate oil-cylinder liner was considered as a coupled component. The cases of applying either the Cu-oil nanofluid or the Cu-water nanofluid was studied and compared with original case. The numerical results showed that the applying of nanofluids could improve the heat load of piston set-cylinder liner. As to the piston, the heat transfer enhancement by the cu-oil nanofluid is greater than Cu-water nanofluid, and the temperature of the first ring decreases notably. For the cylinder liner, the case of using the Cu-water nanofluid exhibits the better capability of heat transfer enhancing. Besides, the Cu-oil nanofluid also shows the potential in improving lubrication and friction of piston rings-cylinder liner contact
