BEYOND NAVIER-STOKES: MEETING THE CHALLENGE OF NON-EQUILIBRIUM GAS DYNAMICS

能够预测流体在高速或小尺度下的行为是各种令人兴奋的未来技术的关键：高马赫数，高空飞行可以改变全球旅行，而纳米和微设备通过在最小尺度上操纵它来改变我们的宏观环境的能力为新的工业革命带来了希望。虽然这些技术乍一看似乎不太可能成为合作伙伴，但它们都需要对极端条件下的流体动力学有深刻的理解/超越当前模型。我们在这个项目中的愿景是通过在分子水平上从气体流动的基本统计力学中建立一个新的动力学模型来提供这种理解。该项目将聘请一名博士后研究助理和一名博士生，并提供适度的差旅和支持费用，我们的研究结果将通过为期一天的公开会议（包括研讨会和讲习班）进行传播，以展示和讨论英国在非平衡流动方面的研究。这次会议还将作为一个论坛，讨论这个研究社区的未来发展和方向。

Being able to predict how fluids behave at high speeds or small scales is key to a diverse range of exciting future technologies: high Mach number, high altitude flight could transform global travel, while the ability of nano- and micro-devices to change our macro environment by manipulating it at the smallest scales holds the promise of a new industrial revolution. While these technologies seem, at first sight, unlikely partners, both require a deep understanding of fluid dynamics under extreme conditions / beyond that of current models. Our vision in this project is to provide this understanding by building a new dynamical model from the fundamental statistical mechanics of gas flows at the molecular level. The project will employ a postdoctoral research assistant and a PhD student, with modest travel and support costs, and our results will be disseminated through a one-day open meeting (comprising seminars and a workshop) to present and discuss UK research in non-equilibrium flows. This meeting will also act as a forum to discuss the future growth and direction of this research community.
