Investigating the thermal behavior of aluminum-oxygen mixture in the presence of Cu walls by molecular dynamics simulation

This research studied the thermal behavior, and combustion process (CP) of oxygen/aluminum nanofluid in a nanochannel with copper walls by molecular dynamics simulation (MDS). From the operational point of view, this research consisted of two main parts, including balancing atomic samples and the CP of atomic structures. By studying the physical balance in the atomic samples by changing the temperature (T), and total energy (TE) curves, the amount of T, and TE in the samples were converged at 300 K and -6692.56 eV, respectively. According to the radius of aluminum nanoparticles (NPs), the sample's heat flux (HF) was 1312 W/m2, and the combustion time is 6.01 ns when the radius of aluminum nanoparticles (NPs) was 10 Å. According to the results of the experiment, increasing the percentage of aluminum nanoparticles (NPs) to 5% led to HF reaching 1355 W/m2, and the combustion time reaching 5.95 ns. Therefore, the outcomes of study showed an enhancement in HF, and a decrease in combustion time by enhancement the amount of NPs, the size of NPs.
