Job description

Boiling and condensation play a very important role in many industrial processes involving heat transfer. Application can be found in power generation, cooling & refrigeration systems and internal combustion engines. At small scale boiling and condensation can be studied in great detail by Direct Numerical Simulation (DNS). Within the Delft University of Technology soft- and hardware tools are available for such detailed studies.

The goals of the present project are to:

  • Further develop and validate DNS sub-models for bubble coalescence and breakup in an in-house DNS code;
  • Develop and validate DNS sub-models for interfacial heat and mass transfer in an in-house DNS code for bubbly flows;
  • Further develop and validate the existing DNS sub-models for boiling which are available in the in-house DNS code;
  • Perform DNS simulations of convective turbulent boiling flows for both laboratory and reactor conditions, and analyse the effect of the different conditions on the convective turbulent boiling flow structures.
  • Develop models that can be used in an industrial setting.

This work will be executed in a co-operation with the Nuclear Research and Consultancy Group NRG in The Netherlands
