Fabrication of highly ordered and dense nanofibers assemblies is of key importance in designing high-performance and multi-functional materials. In this work, we design an experimental approach in silico, combining shear flow and solvent evaporation to establish nanofiber alignment and densification of the assemblies. We demonstrate the feasibility of this approach by performing dissipative particle dynamics simulations, where the hydrodynamic and thermal fluctuation effects are fully modeled. We find that the microstructural order of assembled nanofibers can be established within a specific range of the Peclet number and evaporation flux. The underlying mechanism is elucidated by considering the competition between hydrodynamic coupling and fluctuating dynamics of nanofibers. Based on these understandings, we outline a practical setup to fabricate highly ordered and dense nanofiber assemblies.
