Non-equilibrium Molecular Dynamics

Description

Non-equilibrium molecular dynamics (NEMD) is the study of fundamental fluid flow using molecular simulation - 'non-equilibrium' because the system is driven away from thermodynamic equilibrium by wall motion, temperature and pressure gradients or contains an interface, e.g. a liquid-vapour coexistence.

Second meeting of the NEMD SIG - 6th Sep 2021 Online

Our second NEMD SIG meeting took place on Monday the 6th September 2021 using Microsoft Teams. We had a range of international speakers from Australian, China, India, Europe and the US. We recorded all talks in three parts https://youtu.be/DgAFUfspntY, https://youtu.be/wVHlGTRlmWg and https://youtu.be/lVzD4G1yowE so attendees can catch up on talks they missed. There are also open to the UK fluids community to learn more about NEMD and how it can be useful to their research.

The book of abstracts is here, the program from the day is below where clicking on the speakers name will take you to their website and clicking on the talk name wil go to the video from the day:

From the discussion sessions, we talked about three topics in groups, with the following notes

1. Way forward - how do we get further funding for the next SIG meeting (N.B. we spent £2,000 on this meeting), where do we host the next meeting? What do we want for the focus? 

2. Links between fundamental NEMD work and existing funding areas (EPSRC, ERC, Leverhulme, Royal Society)? Routes to new funds (e.g. setting up a NEMD CDT or creating an MD UKRI theme)

3. Links to industrial problems. How do we demonstrate value for industry? What can we do next with the SIG to encourage this?
