Micro & Nano Flows for Engineering

The micro & nano flows group is a research partnership between the Universities of Warwick and Edinburgh, and Daresbury Laboratory. We investigate gas and liquid flows at the micro and nano scale (where conventional analysis and classical fluid dynamics cannot be applied) using a range of simulation techniques: molecular dynamics,  extended hydrodynamics, stochastic modelling, and hybrid multiscaling. Our aim is to predict and understand these flows by developing methods that combine modelling accuracy with computational efficiency.

Targeted applications all depend on the behaviour of interfaces that divide phases, and include: radical cancer treatments that exploit nano-bubble cavitation; the cooling of high-power electronics through evaporative nano-menisci; nanowire membranes for separating oil and water, e.g. for oil spills; and smart nano-structured surfaces for drag reduction and anti-fouling, with applications to low-emissions aerospace, automotive and marine transport.


EPSRC Programme Grant in Nano-Engineered Flow Technologies

Our work is supported by a number of funding sources (see below), including a 5-year EPSRC Programme Grant (2016-2020). This Programme aims to underpin future UK innovation in nano-structured and smart interfaces by delivering a simulation-for-design capability for nano-engineered flow technologies, as well as a better scientific understanding of the critical interfacial fluid dynamics.

We will produce software that a) resolves interfaces down to the molecular scale, and b) spans the scales relevant to the engineering application. As accurate molecular/particle methods are computationally unfeasible at engineering scales, and efficient but conventional fluids models do not capture the important molecular physics, this is a formidable multiscale problem in both time and space. The software we develop will have embedded intelligence that decides dynamically on the correct simulation tools needed at each interface location, for every phase combination, and matches these tools to appropriate computational platforms for maximum efficiency.

This work is strongly supported by nine external partners (see below).

Jason Reese has been elected Fellow of the American Physical Society (APS) upon the recommendation of the APS Division of Fluid Dynamics. The number of APS Fellows elected each year is limited to no more than one half of one percent of the total membership, so this is a prestigious recognition of Prof Reese’s outstanding contributions to the physics of fluids. 

The citation from the APS recognises Prof Reese “for original contributions to multiscale fluid dynamics research, unique work in rarefied gas dynamics, pioneering hybrid modelling, and simulation methods for flows at the micro- and nanoscales.”

The American Physical Society was founded in 1899 “to advance and diffuse the knowledge of physics”. It publishes more than a dozen scientific journals, including the prestigious ‘Physical Review’ and ‘Physical Review Letters’, and organises more than twenty science meetings each year. The APS conducts extensive programs in education, public outreach, and media relations; APS divisions and topical groups cover all areas of physics research. Forums reflect the interests of its over 53,000 international members in broader issues, and sections are organised by geographical region.

This week, Warwick welcomes two post-doctoral researchers Livio Gibelli and Juan Padrino. Livio has a long track record in the development and applications of kinetic theory; he joins us from Politecnico de Torino. Juan has made contributions to a broad range of fields, in particular, potential-flow modelling of viscous fluids; he joins us from Los Alamos National Laboratory. This is a picture of the whole Warwick team together after Juan and Livio's welcome lunch...

Jun gave an invited talk at Institute of Mechanics, Chinese Academy of Sciences on January 4th, 2017. His talk was titled "Molecular simulation and multiscale modelling of nonequilibrium and noncontinuum flows" (in Chinese: 非平衡和非连续流的分子统计模拟与多尺度计算), and was given in front of audiences numbering about 50. The topics include his recent works on droplets and previous works on rarefied gas dynamics.

Here is an interesting article on the most prominent trends in the world of high performance computing in the last one year, discussing topics from machine learning to new processors to exascale.

And here is the latest TOP500 supercomputer list published in November 2016, for those not already aware of it.

This lists and ranks the 500 most powerful computer systems in the world. The first list goes back to 1993. TOP500 publishes an updated list of the supercomputers twice a year - the first happens in summer during the International Supercomputing Conference (ISC) in Germany, and the second one is presented  at the Supercomputing Conference (SC) in November each year.

Check out this video showing how liquid droplets, upon reaching some critical velocity, can have their shape 'frozen' upon impacting a solid surface coated with a superhydrophobic powder. These experiments were carried out by J. Marston et. al. at the King Abdullah University of Science and Technology, who have written multiple articles discussing the results of their experiments.
