Comparison of wind pressures on a mobile home in model and full scale.

Compares wind pressures measured on a 1:25 scale model of a mobile home with results from a full-scale investigation. The modelling technique used exaggerates the surface roughness in order to match the full-scale turbulence intensity at the model height. Shows that there is reasonable agreement of themean and RMS pressure coefficients between model and full scale, when the pressure coefficients are normalized by the local dynamic head at the building height. The spectra of the pressure fluctuations in regions of separated flow are not simulated correctly, owing to the absence of largr-scale turbulence in the wind-tunnel boundary layer.
