Abstract |
A panoramic-PIV system has been constructed for the analysis of the airflows in a room. Smoke is used as seeding particles and are visualized by a pulsed laser(Nd-Yag, 120mJ). Panoramic images have been obtained by an image composition process using the two images obtained by the two cameras(1k×1k) that are viewing the wide measurement areas. Velocity vector fields have been obtained by the grey-level cross-correlation PIV method. Three room models(L×W×H[mm3], 500×500×250, 350×350×175, 250×250×125) have been tested. The experimental results have proven that the constructed panoramic-PIV system can be used as a useful tool for analyzing the airflow characteristics in the room models. |
