Abstract: An experimental database for computational fluid dynamics (CFD) code validation is indispensable. However, the example made by the low-turbulence natural convection field becomes dominant where the subject is little. Therefore, an experimental study was conducted by using particle image velocimetry (PIV) in a model of a floor-heating room. Furthermore, the results of CFD analysis were compared with the experimental data. Wind-velocity measurement using PIV was conducted for grasping the natural convective field in a floorheating room model and expansion of the wind-velocity database for CFD-code validation. It was confirmed that PIV was mostly able to obtain the air-current properties of the natural convective field in the floor neighborhood.
