| Abstract: | The nanofluid is a two-phase suspension that consists of a base liquid and suspended nanoparticles. A number of acting forces such as drag force, Brownian force, dispersion force and gravitational force affect flow behavior of the suspended nanoparticles, which complicates description of nanofluid flow. The lattice Boltzmann (LB) method is used to develop a model for the nanofluid and to investigate flow structure of nanofluids and heat transfer inside the nanofluids with taking these forces into account. Flow patterns and the temperature profiles of the sample nanofluid are simulated. |
