Applications are invited for a research associate position to work at Imperial College London, in the South Kensington Campus, as part of the Enhanced Multiscale Boiling Surfaces (EMBOSS) project; this is a £1.7m programme in collaboration with the University of Brunel, and the University of Edinburgh. EMBOSS will combine experimental and computational techniques, spanning the scales from molecular to millimetres, and will inform the rational design, fabrication, and optimisation of operational prototypes of a pool-boiling thermal management system. The main role of the post holder will be to carry out research in the area of molecular modelling and molecular dynamics (MD) simulations relevant to boiling and two-phase heat transfer applications. Of crucial importance is to couple the MD work at the nucleation scale to meso- and macro-scale models in terms of the flow and thermal fields, as well as interface shape (of the nucleated, growing bubble), taking into account substrate properties. The numerical tools to be developed as part of EMBOSS will ultimately allow simulation of bubble nucleation, growth, and detachment from multiple sites on substrates with well-defined geometry and wettability in order to optimise boiling heat transfer.

The successful candidate should hold a PhD in Chemical or Mechanical Engineering, applied mathematics, Computer Science or a closely related discipline. (S)he should have a strong background in molecular simulations, knowledge and experience with computational fluid dynamics (CFD); mulit-scale modelling; coupling of micro-scale to larger-scale models; heat transfer, boiling/phase change, two-phase flows, statistical mechanics, and machine learning is desirable. (S)he should have considerable experience in developing models, numerical tools, and writing computer programs. (S)he should have knowledge of programming languages (e.g. C++, FORTRAN 90, Python), parallelisation (MPI), and open-source software, e.g. LAMMPS, OpenFOAM.

It will be expected that the post-holder will interact closely with the numerical modelling (and experimental) effort in the Matar Fluids Group. There will also be opportunities to collaborate with researchers working as part of the EMBOSS programme at Brunel and Edinburgh on meso-scale (lattice-Boltzmann method) modelling, CFD (interface-capturing and level-set method) simulations, and experiments, as well as on manufacturing of smart boiling surfaces. There will also be regular interactions with the EMBOSS industrial partners, particularly in terms of the dissemination of the EMBOSS results, and technology transfer. Finally, the post-holder will also interact with the multi-sector industrial collaborators of the Matar Fluids Group.

*Candidates who have not yet been officially awarded their PhD will be appointed as Research Assistant within the salary range £33,380 – £35,061 per annum.

The post is available immediately. The appointment is for 36 months, based in the Department of Chemical Engineering, Imperial College London (South Kensington Campus).

Informal enquiries about the post can be made to Prof Omar Matar (
