Numerical thermal analysis and optimization of multi-chip LED module using response surface methodology and genetic algorithm

In this paper, the heat transfer performance of the multi-chip (MC) LED module is investigated numerically by using a general analytical solution. The configuration of the module is optimized with genetic algorithm (GA) combined with a response surface methodology. The space between chips, the thickness of the metal core printed circuit board...

Optimal use of the subsurface for ATES systems in busy areas

With the incentive to reach the energy saving and CO2 emission reduction targets of the Netherlands, the application of Aquifer Thermal Energy Storage (ATES) is expected to increase sharply during this decade [2]. With limited aboveground and underground space, well arrangement is becoming difficult in busy areas with a rapidly growing number of...
