Promoter: Johan Meyers
details
Description: OPTEC (K.U.Leuven Optimization in Engineering Center), and the department of Mechanical Engineering (division TME) offer a grant for candidates who want to pursue a PhD in engineering, and gain teaching experience as a member of the didactic team of the mechanical engineering department.
The candidate aims at a PhD in engineering with research topic: efficient parallel optimization algorithms for transient three-dimensional turbulent-flow simulations (DNS and LES) with applications towards turbulent mixing.
The PhD research focuses on the development of efficient optimization algorithms for parallel computing of complex three-dimensional transient flow simulations, with applications oriented towards turbulent mixing in the presence of passive scalars with and without buoyancy effects. For the flow simulations direct numerical simulations (DNS) and large-eddy simulations (LES) are considered. First of all, the use of algorithms such as BFGS, multiple shooting, multigrid, and various continuation methods are elaborated for large-scale flow optimization on high-performance computing systems. Next to that, the research will concentrate on algorithms which may improve on local optima found using gradient-based optimization techniques (e.g. using a combination with simulated annealing). Finally, the effect of uncertainty, and the presence of background turbulence, on optimization algorithms is investigated.
The research is funded by OPTEC (an excellence center on optimization at K.U.Leuven -
www.kuleuven.be/optec/), and is well integrated in OPTEC's research structure, in particular in Working Group 6 on PDE-constrained optimization. The research further closely relates to the fluid-mechanics research at the Mechanical Engineering Department (supervised by Prof. J. Meyers), and the algorithmic research on PDE-optimization at the Computer Science Department (Prof. S. Vandewalle).

Research environment:
The Mechanical Engineering department of the K.U.Leuven has an excellent research track in both fluid mechanics in general
and turbulent flow optimization. The K.U.Leuven, situated in Leuven near Brussels, is one of the oldest universities in Europe. Its rich history
and patrimony provides an inspiring research environment, and this is combined with very high standard accommodation. For its computational research,
the K.U.Leuven has a state-of-the-art cluster, 20 TFlops system with 1500 Intel Xeon cores, which is part of the Flemish Super Computing Center.
Leuven is a very agreeable city that is excellently geared to serve almost 30,000 students. The Mechanical Engineering building is situated on its perimeter in a peaceful green park near an ancient Castle. For more information, visit
