Abstract
A numerical simulation model has been developed for the transient flow and heat transfer problems of oil inside the piston gallery using a coupled VOF/Level Set method. Detailed cooling processes of Cu-oil nanofluids, with the nanoparticle size of 50 nm and the volume fractions of 1, 2 and 3 %, have been investigated. The oil fill ratio (OFR) and heat transfer coefficients (HTC) variations at different crank angles have been examined as well. The results have demonstrated that the nano-oil is able to improve the heat transfer capacity by a large margin. Compared with the conventional engine oil, the overall average heat transfer coefficients of the nano-oil, with the volume fractions of 1, 2 and 3 %, increase by 5.80, 14.51 and 28.11 % respectively.
