Abstract
This study presents an experimental and numerical investigation of the performance of a forced draft counter flow cooling tower with two kinds of wire mesh packing. The packing used in this study is wire mesh with small square holes (WMSSHSP) and expanded wire mesh with diamond holes (EWMDHSP) configurations. In the numerical investigation, the two dimensional CFD model with finite volume scheme has utilized the standard (k-ε) turbulence model to computes the air properties, while one-dimensional model is usedto get the water properties. From the results it is concluded that the (EWMDHSP) enhance the performance of the cooling tower. That is due to the pressure drop in the (WMSSHSP)is higher than that for the (EWMDHSP) because air resistance of the former pack is higher than the latter pack.The agreement seems to be acceptable between the numerical and the experimental results.
