Session Abstract


The use of computational fluid dynamics (CFD) for indoor and outdoor airflows and related heat and mass transport in the built environment has increased tremendously in the last decades. Despite the increase of computational power, there is a need for faster and more efficient numerical methods than the conventional CFD method, especially for cases with highly transient flow features which would otherwise require the use of the computationally demanding large-eddy simulation (LES) approach. Besides, the accuracy of conventional CFD methods can be limited in some instances and efforts are needed to increase this accuracy efficiently.


The aim of the workshop is to present an overview, the progress, and the advantages and disadvantages of four different non-conventional/traditional numerical approaches to predict airflows, heat and mass transfer in the built environment, namely: (1) fast fluid dynamics (FFD); (2) lattice Boltzmann method (LBM); (3) CFD with data assimilation (CFDA); (4) voxel-based CFD. The presentations will be followed by a discussion on future directions for both academia and practice.
