SBIR Phase I: Continuous Production of Nanofluids by Flame Aerosol Process

这个小企业创新研究第一阶段项目将展示一种创新的液体燃烧工艺的发展，该工艺用于连续生产纳米流体，该纳米流体含有悬浮的、尺寸和成分均匀的未团聚金属和非金属纳米粉末。已经证明，含有固体金属纳米颗粒的流体——纳米流体——与传统的传热流体相比，表现出显著增强的导热性。这项工作的一个相关目标是开发一种新的大涡模拟（LES）模型，用于纳米颗粒的形成和聚集，该模型与局部分子动力学（MD）和蒙特卡罗（MC）模拟模型相结合。该数值工具将用于设计工艺参数，以产生所需的粒度分布。纳米流体的使用可以影响许多工业部门，包括运输、电子、能源供应、纺织等。几乎所有拥有热管理系统的部门都将从该项目中受益。

This Small Business Innovation Research Phase I project will demonstrate the development of an innovative liquid combustion process for continuous production of nanofluids with suspended unagglomerated metallic and non-metallic nanopowders of uniform size and composition. It has been demonstrated that fluids containing solid metallic nanoparticles -nanofluids- display significantly enhanced thermal conductivities relative to conventional heat transfer fluids. A related goal of this effort is the development of a new large-eddy simulation (LES) model for nanoparticle formation and aggregation coupled to local Molecular Dynamics (MD) and Monte Carlo (MC) simulation models. This numerical tool will be applied to design process parameters to produce the desired particle size distribution. The use of nanofluids can impact many industrial sectors, including transportation, electronics, energy supply, textiles etc. Mostly all the sectors that have thermal-management systems will benefit from this project.
