This study analyzes the heat transfer characteristics of various nanoaerosols on a two-dimensional model of pipe flow subjected to the velocity inlet, pressure outlet, and constant heat flux on the pipe wall. The Eulerian multiphase model was selected to simulate the problem with 50 nm particle size at 0.01 vol. fraction at Re from 8,000 to 20,000. The rise of Reynolds number in the selected range is influential enough to raise the aerosol heat transfer coefficient by 108%. The heat transfer coefficients of MgO, SiO₂, and TiO₂ nanoaerosols are better than ZnO and Al₂O₃ nanoaerosols by 23.27, 16.57, and 11.39%. In comparison to TiO₂ nanoaerosols, SiO₂, MgO, ZnO, Al₂O₃ nanoaerosols exhibited 52, 48, 26.8, and 14 times enhancements in particle migration factor, respectively.
