VO2 nanoparticles have attracted significant research interest for energy-saving smart window applications due to their ability to selectively block infrared heat while transmitting visible light. These VO2 nanoparticles are synthesized using a continuous-flow hydrothermal mixing reactor which must operate at supercritical conditions. However, experimental results have indicated that the optical properties of the as-synthesized VO2 nanoparticles are dependent upon the dimensions and relative uniformity of nanoparticle sizes, which are in turn a product of the degree of mixing during synthesis. Therefore, this current work leverages computer simulations to determine the optimum reactor design and boundary conditions which are most conducive to uniform mixing during nanoparticle synthesis. Initial results indicate that, given the current reactor design and operating parameters, the VO2 nanoparticles do not undergo uniform quenching, which could give rise to non-uniform nanoparticle sizes and inconsistent optical properties.
