Simulation Study on the Production of Nano-Sized Materials at Mixing Stage

Abstract:

There is a growing interest in unique-sized nanomaterials in numerous engineering applications due to their properties such as a very high surface area to volume ratio and effect of quantum confinement. The aim of this paper is to investigate the fluid flow profile at various levels reaction time in the mixing stage during the process of production nanosized materials using an effective numerical approach. Therefore, virtual modelling techniques were employed to model the internal flow in the mixing stage. Pre-processor software, GAMBIT 2.4 was used to create the mixer model and generate the meshes. Then, the model was exported to FLUENT 6.3.26 for further fluid flow analysis. A maximum pressure of 300 bars was applied to produce nanosized material in the mixer. The simulation results revealed that the inlet pressure yielded the great impacts on the production of nanosized material. The effects of inlet pressure on different reaction time significantly influence the flow behaviour as clearly showed in the simulation result. Thus, this study is expected to provide valuable guidelines to any nanoscale industries during production process and further analysis were needed in this field of study.
