Fractal Aggregation Simulation in the Nanofluid Drying

Nanofluids are kinds of fluids engineered by dispersing nanoparticles in base fluids. After full evaporation drying of nanofluids, the nanoparticles are left on the substrate and can self-organize in different structures on the substrate. The fractal-like branched structures can be formed, these phenomena are simulated in the study. Two dimensional lattice-gas model is applied in the process of the residual thin film evaporation drying. The Monte Carlo simulations show the formation of well-developed fractal aggregates for this configuration. The results of simulations are in good agreement with previously reported experimental results in residual nanofluid thin-film drying.
