Abstract

Developing materials that efficiently combine cutting-edge technology with competitive costs so as to meet technical, economic and, last but not least, environmental challenges are a must in the field of materials engineering and beyond. Ionic liquids are heat transfer fluids that offer a wide range of advantageous properties. One of the most recent applications of these complex ionic liquids and nanomaterial systems is the ionanofluids. In this paper we performed a numerical study of the laminar flow of a fluid through a pipeline, accompanied by thermal transfer. The problem is typically addressed by validating the model on experimental bases and then implementing four less studied fluids, namely two ionic liquids and two ionanofluids (obtained by adding 1% multi walled carbon nanotubes). The numerical results presented confirm the theory of the definite advantages of adding nanoparticles to conventional liquids.

摘要

开发将尖端技术与具有竞争力的成本有效结合的材料，以应对技术、经济和环境挑战，这在材料工程及其他领域是必不可少的。离子液体是具有广泛优势特性的传热流体。这些复杂离子液体和纳米材料系统的最新应用之一是离子流体。在本文中，我们对流体通过管道的层流进行了数值研究，并伴随着热传递。该问题通常通过在实验基础上验证模型然后实施四种研究较少的流体来解决，即两种离子液体和两种离子流体（通过添加 1% 多壁碳纳米管获得）。
