This paper presents a comparative study on oil fill ratio and heat transfer coefficient within the steel piston cooling gallery for engine oil containing TiO2 and CuO nano-additives, respectively, by using Ansys fluent package. Both nano-additives of 50 nm diameter are added individually in engine oil in proportion of 1%, 2% and 3% for CFD analysis of oil flow and heat transfer process. The evaluation is carried out considering 2100 rpm engine speed. Also, the empirical value of heat transfer coefficient has been calculated.
In modern combustion engines, the pistons are subjected to very high thermal loads
as modern engines are being used for high specific power output. With the aim of
ensuring operating safety, the pistons must be cooled as adequately as possible. In
order to provide effective heat dissipation from the piston and keep the temperature
down in critical zones of piston, pistons with different types of cooling are used
instead of uncooled piston. In general, engine oil is used as coolant in all piston
cooling methods.
The paper studies the heat transfer process of engine oil with the addition of
copper and titanium nanoparticles inside a steel piston cooling gallery by CFD analysis.
