Abstract

The paper is aimed at building an appropriate Computational Fluid Dynamics (CFD) model for simulating the flow field in the office cubicle with and without personalized ventilation (PV). A computational model was first constructed by using a commercial CFD code (STAR-CCM). In this process, different approach of representing manikins, boundary conditions, geometries, and gridding were tested, and a proper approach selected for simulating the air and contaminant movement in the cubicles and their interactions with the remaining room space. A comparison between the simulation and the experimental results are made to show how accurate the CFD model can be. A brief evaluation of the environment quality was conducted for both cases with PV and Underfloor Air Diffuser (UFAD) and the comparison showed a huge advantage of the PV system.
