About the Thesis Work
The Fluid Dynamics team within the Energy Transfer & Environment (YRLE) department at Vattenfall Research and Development is a multidisciplinary group that covers all aspects of fluid flow relevant to Vattenfalls operations from river hydraulics to offshore wind power and nuclear energy.
Subject/Assignment:
Heat transfer in multiphase-phase flow involves complex physics. Depending on the industrial process the phases can be any combination of liquids gases and solids at different concentrations. The phases can either be separated sharing a single interface or several phases may be dispersed into one-phase resulting in many many industrial processes there is one continuous phase and one or several dispersed phases. This is the case for the spray cooling of steam in the pressurizer in pressurized nuclear reactors (PWR) see figs.
Within the AdTherm competence centre (AdTherM Advanced computing for sustainable thermal management in industry) work package 3 is concerned with multiphase flows and particularly steam condensation through spray cooling and subsequent spray-wall interaction and heat order to understand the limitations of current state-of-the-art computational models a set of simulations with different flow turbulence spray drop and thermodynamic models should be performed using OpenFOAM and evaluated using tailored experiments made in the Älvkarleby laboratory. Participation in some experimental work is also possible and encouraged.
Goal/Purpose:
Understand the current state-of-the-art for computational models multiphase flows including droplets steam condensation and spray-wall interaction and heat transfer

Diversity and Inclusion In Everything We Do
We are convinced that heterogeneous teams can outperform homogeneous ones. But we can only unlock the power of diversity when everyone feels included. Read more about our important work on diversity and inclusion at Vattenfall
At Vattenfall we are determined to enable fossil freedom. To succeed we must first become fully fossil-free ourselves as one of Europes largest energy companies. But that is not enough. To contribute to a fossil-free society we need to do more than just focus on sustainable energy production.
We believe that enabling fossil freedom requires us to address the challenge from a broader perspective than merely producing energy sustainably.
Join us on the journey towards fossil freedom.
As Vattenfall is part of Swedens critical infrastructure many of our roles are security-classified. This means that if this position is security-classified final candidates may be subject to a special security clearance in accordance with the Security Protection Act.
