Energy efficiency optimization by multi-scale approach
Increasing energy efficiency is one of the key challenges for energy systems.This paper presents my strategy for optimising energy efficiency through a multi-scale approach,and some supporting examples to illustrate our related research work.A multi-scale approach has been developed and applied,involving three scales:local scale,component scale and system scale,each with its own performance criteria to be treated appropriately and using original optimisation methods.More specifically,the objectives are:(1)local scale,to intensify heat and mass transfer by controlling transport mechanisms at interfaces using original shape and topological optimization methods;(2)component scale,to design and develop innovative fluidic,thermal and reactive components through their structural optimisation and fluid flow distribution management;(3)system scale,to develop compact,modular,integrated and multi-functional energy systems for energy production,storage and utilisation,and to maximize their global performance with minimum impact of dissipations;(4)for scale transition,to seek structural,functional and temporal synergy effects through appropriate scaling laws.Some illustrative examples are presented in detail to illustrate the proposed strategy,which is expected to provide a novel approach and a powerful tool for academic research,R&D centres and various industries in many energy systems and processes.
