... stability. Introduction Nanofluid is a novel heat- transfer fluid prepared by dis- persing nanometer-sized solid particles in traditional heat- transfer fluid to increase thermal conductivity and heat- transfer performance. ... 50°C, respectively. As the heat transfer in solid-liquid suspen- sion occurs at the particle-fluid interface [18], an increase of the interfacial area can...

Each of the filters is using a different state transition model, namely, static, constant ... than Cartesian coordinates in our simulations. Empirical results demonstrate the effectiveness of using the temporal information. Finally, we emphasize that only a sim- plified model was us...
