- Two-phase cooling of electronic components
Contact: Tom
Saenen - Martine Baelmans
Driven by miniaturization and the continuing increase in clock
speed and data transfer conventional cooling of electronics has
reached its limits. Two-phase micro scale cooling is envisaged as a
cooling method that has the potential to cool next generation
electronics. Different aspects of two-phase micro scale flow and
heat transfer will be studied to be able to produce a two-phase
heat sink with cooling rates up to 500 W/cm2 or possibly
even higher.

Research topics
- Optimal control of turbulent mixing
Contact: Sara
Delport - Johan Meyers -
Martine
Baelmans
Turbulent mixing occurs in various industrial applications. By
changing the turbulent flow features, the efficiency of industrial
installations may be drastically improved. We employ optimization
techniques combined with DNS and LES to achieve these goals.
- Computational aeroacoustics of muffler noise using
large eddy simulations
Contact: Peng
Wu - Johan
Meyers - Martine Baelmans
Computational aeroacoustics (CAA) calculations of the flow-induced
noise emitted by mufflers in stationary and pulsating flow using
large eddy simulations (LES) are performed.
- Proper Orthogonal Decomposition (POD) methods for
Aeroacoustics [Poster]
Contact: Vladimir
Jovanovic - Johan Meyers -
Martine
Baelmans
Fully developed compressible turbulent flows over open cavities are
dominated by the large scale coherent structures (CS). Those appear
to be the most energy containing and responsible for the
aerodynamic noise generation. Proper Orthogonal Decomposition (POD)
is a post-processing method which is to be applied upon the data
obtained from 3D DNS/LES open cavity numerical simulations.
- Quality and reliability of large-eddy
simulations
Contact: Johan
Meyers The error behavior of subgrid-scale modeling and
numerical discretization in large-eddy simulation is studied.
Modifications of subgrid closures which account for numerical
errors, and improve simulation quality, are investigated.
- Computational and Experimental analysis of a wide
cleaning fan for a harvester
Contact: Mekonnen
Gebreslasie - Johan Meyers -
Martine
Baelmans - Josse De
Baerdemaeker
This PhD research focuses on computational and experimental studies
to improve the grain cleaning ability of a wide cross-flow fan for
the second cleaning system in a combine harvester.
