dc.description.abstract | Introduction. Design optimisation using Computational Fluid Dynamics (CFD) often requires extremising multiple (and
often conflicting) objectives simultaneously. For instance, a heat exchanger design will require maximising
the heat transfer across the media, while minimising the pressure drop across the apparatus. In such
cases, usually there is no unique solution, but a range of solutions trading off between the objectives. The
set of solutions optimally trading off the objectives are known as the Pareto set, and in practice only an
approximation of the set may be achieved. Multi-Objective Evolutionary Algorithms (MOEAs) are known to
perform well in estimating the optimal Pareto set. However, they require thousands of function evaluations,
which is impractical with computationally expensive simulations. An alternative is to use Multi-Objective
Bayesian Optimisation (MOBO) method that has been proved to be an effective approach with limited
budget on function evaluations [1]. In this work, we illustrate a newly developed MOBO framework in [1]
with OpenFOAM 2.3.1 to locate a good estimation of the optimal Pareto set for a range of industrial cases. | en_GB |
