Boltzmann transport applications meeting

10:00 - 16:30, Wednesday 4th December 2019

The meeting is centred on bringing together academics and industry that work on solving Boltzmann-type problems in a range of different application areas. The idea behind this meeting is to try and foster collaboration between different disciplines, to exchange knowledge on methods and tools and help improve all our abilities in tackling difficult multi-dimensional Boltzmann problems.

This year, the meeting will be hosted by the Applied Computational and Modelling Group (AMCG) at Imperial College London and we believe would be of interest to mathematicians, scientists and engineers in fields as diverse as:

The meeting will be comprised of a series of 20-30 minute talks, along with focused discussion sessions. The first talk in the morning session will give an introduction to Boltzmann transport modelling in different applications, with the aim of setting a common language to facilitate discussions that follow.


Imperial College London
Royal School of Mines building
RSM 1.51 (Level 1)



Steven Dargaville (Imperial College London) and Tom Deakin (University of Bristol)


This is the rough plan for the day, but the timings are flexible to allow plenty of time for discussions.
