Numerical Simulation of the Nanofluid Phase Separation by Lattice Boltzmann Method

Abstract:

Using shan-chen model of lattice Boltzmann method,considering the interaction between nanoparticles and base fluid, by modifying the nanofluids single-component multiphase model, established the nanofluid multi-component heterogeneous lattice Boltzmann model. The model was used to simulate square cavity phase separation of nanofluids, get the Nanofluid separation phase diagram, compared it with pure water phase separation diagram, the results show that, nanofluid in gas-liquid two phase separation process, the addition of nanoparticles is beneficial to produce bubbles, meanwhile the addition of nanoparticles caused a micro convection inside the base fluid, improved the performance of the spread of the base fluid, leaded to the transmission effect, hindered the coalescence of bubbles.
