摘要
Nanofluids are kinds of fluids engineered by dispersing nanoparticles in base fluids, a new challenge for thermal sciences provided by nanotechnology. Due to their excellent characteristics, nanofluids find wide applications in enhancing heat transfer. This paper presents synthesis and characterization of TiO2-CNTs nanocomposites by sonochemical method and investigation of some properties of TiO2-CNTs nanocomposite suspended in 50:50 (by weight) propylene glycol and water mixture as a new nanofluid. 2012 JNS All rights reserved
