The 3-year fully funded PhD position is part of the project “Establishing next-generation pioneering models 
for interface mass transfer, breakup and coalescence in turbulent flow”, funded by the Norwegian Research 
Council. 

The understanding of droplet dynamics in turbulent flow is important for a variety of industrial processes. In 
this project we are interested in the detailed analyses of drop-turbulence interactions. We are particularly 
interested in understanding the drop-turbulence interactions in the cases where such interactions result in 
breakup of droplets. Numerical simulations of turbulent flow (resolved scales) with dispersed droplets 
(described by the phase field method) can provide the necessary flow fields needed to analyse the drop-
turbulence interactions. Canonical flows such as the channel will be adopted for the multiphase flow 
simulations.

The qualified candidate must have deep interest in high-performance computations of physical phenomena of 
multiphase turbulent flows. This requests that the candidate must hold good knowledge of turbulence theory. 
The work will include programming (modification and further developments of existing codes). Basic codes 
written in Fortran will be provided to the candidate. The candidate must expect to communicate the work to 
both the research group at NTNU and international collaborating groups. The position will include stay abroad 
(3-6 months) with collaborating groups, mainly TU Madrid.

The applicant must describe her/his experience with turbulence statistical analyses. In particular, the 
applicant must clearly state her/his experience with turbulent coherent flow structures, Q-criterion, lambda-
criterion, proper orthogonal decomposition, Lagrangian methods, or other relevant methods.
