Numerical Nanofluid Simulation with Finite Volume Lattice-Boltzmann Enhanced Approach

In this paper, the finite volume Lattice-Boltzmann method is used to model the thermo-fluid behavior of nanofluid, in which nanoparticles are dispersed. The major internal and external forces including Brownian, repulsion and attracting DLVO, drag and buoyancy acting on nanoparticles are taken into account. All these forces make the thermal and dynamic mechanism inside the nanofluid improved. These models are established to simulate and enhance the heat transfer properties of nanoparticles in the CuO-H۲O nanofluid as a test case. Also, convective heat transfer coefficient of the nanofluid is computed in different Reynolds numbers. The numerical approach is based on a modified and robust finite volume method.
