Postdoc in Multi-Scale, Multi-Phase, Multi-Physics Modelling of Heat and Fluid Flow Conditions Inside Porous Structures

DTU Construct

Applications are invited for a 3-year Post Doc position starting at the end of 2022 within the field of multi-scale, multi-phase, multi-physics modelling of heat and fluid flow conditions inside porous structures. The position is part of the “Towards extreme heat transfer – combining multiphysics-multi scale modelling, topology optimization as well as superconductive materials” project financed by the Independent Research Fund Denmark and carried out at the Department of Civil and Mechanical Engineering at the Technical University of Denmark with collaborators such as The Frauenhofer Institute, Germany.

The project considers the multi-scale improvement of extreme heat transfer devices by optimizing material composition, material microstructure and meso-structure for applications such as wicked heat pipes. This, among other, includes advanced multiphysics modelling of heat and fluid flow conditions over numerous length scales as well as during phase changes.

Responsibilities and qualifications
The objective of optimizing micro- and meso-structural heat transfer requires insight into the modeling of thermo-fluids as well as phenomena such as evaporation and condensation i.e. two phase flows. You will be responsible for the development of an advanced and calibrated multi-phase and multi-scale computational fluid dynamics model (CFD) that covers the determining, involved physics in heat pipes at both macro-scale and meso-scale. This will entail models at meso-scale based on representative volume elements (RVEs) which will feed data into models for the overall thermal performance of the heat pipes at macro-scale. The work will involve detailed validation and calibration against dedicated experiments.

Candidates should document experience within several of the fields: computational fluid mechanics, computational heat transfer, two-phase flow, flow in porous media as well as the finite volume method.

In addition to the direct project related research, you will conduct teaching related activities, disseminate your research through publication of papers and attending conferences and internationalize by a research stay abroad.

We envision that:

  • You have an open mind and can think creatively in a thermo-fluid-mechanical, computational and programming context
  • You are eager to elaborate on the newest research results, improve the ideas and test them by implementation.
  • You have experience within computational fluid dynamics as well as computational heat transfer from either developing your own codes and/or the use of commercial software packages such as OpenFOAM, ANSYS Fluent or Flow 3D.

As a formal qualification, you must hold a PhD degree (or equivalent).
