The Study of New Type of Double Metal Nanofluids Suspension Stability
This paper made two types metal nanoparticles whose laws of motion had bigger different into ethylene glycol became a new type of double metals nanofluids coolant, and through theoretical analysis and experimental observations to research the different of aggregation properties with single metal nanofluids coolant. Research results of theoretical analysis showed that particles motion laws were the important element of nanoparticle aggregation, because of differences in movement, as the same conditions, double metals nanoparticles had the advantage of aggregation number and equivalent diameter of poly group better than single metal nanoparticles. Experimental results showed that through light beam transmittance test, we knew that the transmitting light degree of homogeneity of double metal nanofluids coolant was better than single metal nanofluids coolants; through contrast TME photos, we got nanoparticle aggregation state of three types of metal nanoparticles, and knew the otherness of nanoparticle aggregation state between double metal nanoparticles and Cu nanoparticles and Ag nanoparticles. This paper provides a scientific attempt to solve nanoparticles aggregation.
