Doctoral dissertation Kim Goethals

Convective heat transfer modelling in offices with night cooling

Kim Goethals obtained in 2012 a doctorate in engineering: architecture. His dissertation dealt with “Convective heat transfer modelling in offices with night cooling” (supervisor: prof. A. Janssens). He examined whether building designers are able to accurately predict the performance of night ventilation with today’s dynamic building energy simulation programs (BES) and investigated the influence of the room/system design of a generic landscape office on the convective heat transfer during night ventilation. During the investigations he did experiments in a PASLINK cell and he performed BES and CFD simulations. His results revealed the defect of the BES approach to model the convective heat transfer and illustrated the far-reaching impact of the room/system design on the night ventilation performance. Kim Goethals finally proposed to couple BES with CFD based surrogate models.
