Atomic rheology analysis of the external magnetic field effects on nanofluid in non-ideal microchannel via molecular dynamic method

摘要: In the present study, molecular dynamics method is used to probe aggregation phenomenon of hybrid nanoparticle within platinum microchannel with pyramidal barriers. simulations, argon atoms are described as base fluid particles and for interaction between these atoms, we use Lennard-Jones potential, while platinum–platinum Al2O3 nanoparticles interactions simulated applying embedded atom force field. To analyze achieved simulation results, some physical parameters such potential energy, temperature, distance center mass calculated. The results show external magnetic field decrease in nanoparticles. Numerically, by adding box, COM reaches 2.7 A time changes from 1.7 2.3 ns. These appropriate effects our computational study can be design heat transfer applications.
