In this paper, the flow field in human's respiration area was examined through the PIV (Particle Image Velocimetry) experiment using an experimental thermal manikin and CFD analysis, with the assumption of steady inhalation and unsteady breath. In the CFD analysis, the variation of the air-velocity distribution, and the influence of the exhaustion on the inhalation were examined in detail. Moreover, to account for the influence of the three-dimensional forms of the human body, a model that replicated the actual forms of a real human body was used in the simulation. It indicates that each breathing cycle can be taken as an independent process and the real breathing can be assumed as steady inhalation in CFD analysis on inhaled air region. Moreover, the CFD method using a human body with a complex shape indicates to be effective in the study on the flow field in human's respiration area.
