Detection of steady flow zone with a cooling pad using wind tunnel

The present research work has been carried out on the effect and relation of various parameters on cooling efficiency with minimum water and power consumption by Direct Evaporative Cooler. In this paper the emphasis has been given on the steady flow zone detection in wind tunnel with wet cooling pad of wood wool. The paper presents the experimental results for a 15 and 25 mm thick wet cooling pad. The experimental result shows the steady flow of air has been 340 mm away in wind tunnel with cooling pad. The experimental results have been used to measure cooling efficiency and water consumption with respect to unsteady and steady flow zone.
