This study discuss the application of Taguchi method in assessing maximum cooling tower effectiveness for the counter flow cooling tower using expanded wire mesh packing. The experiments were planned based on Taguchi?s L27 orthogonal array .The trail was performed under different inlet conditions of flow rate of water, air and water temperature. Signal-to-noise ratio (S/N) analysis, analysis of variance (ANOVA) and regression were carried out in order to determine the effects of process parameters on cooling tower effectiveness and to identity optimal factor settings. Finally confirmation tests verified this reliability of Taguchi method for optimization of counter flow cooling tower performance with sufficient accuracy.

The purpose of this study was to determine the effect of fluid velocity and the distance between zig zagfilters on the cooling tower by varying the distance between zig zag foam bio filters. In this study using bio filterfoam material in the form of zig zg by using wire mesh where the tested distance is 5cm, 10cm, and also 15cm. Thenthe water is heated using a heater until it reaches a temperature of 40ºC and then the water is flowed up with a pipeusing a pump and released using a nozzle, then the hot water will go down to the reservoir by passing the bio filterfoam filter that has been installed with a distance of 5cm , 10cm and 15cm. Where there is also a disposal valve thatis done that is closed and faucets are also open ½ and fully open. Good cooling value is indicated by good results oncooling or also cooling faster which is 5cm which results in an average cooling value of 36.53 ºC when the exhaustvalve is fully open, while the value is not good or less optimal cooling it is shown when the drain valve is closed at azig zag distance of 10cm and also 15cm which yields 37.60 ºC data at a zig zag distance of 15cm.

This paper presents an experimental work, which studies the performance of a counter-flow type cooling tower. The experimental trials have been carried out in a counter-flow type cooling tower test rig with mechanical draft. Expanded Wire Mesh type of film packing has been used for experimentation. The packing is made of mild steel with height ranging from 800 to 1255 mm. This study investigates the effect of the air and water flow on the cooling tower range, as well as the tower characteristics for different air flow and water flow quantities. The variation of temperature along the height of pack is measured by means of suitable thermocouples at five different places. The results show that the mass flow rate has adverse effect on the number of transfer unit. Also tower range would be increased by decreasing the inlet wet bulb air temperature.

Based on the basic theory of water droplets impact noise, the generation mechanism and calculation model of the water-splashing noise for natural draft wet cooling towers were established in this study, and then by means of the custom software, the water-splashing noise was studied under different water droplet diameters and water-spraying densities as well as partition water distribution patterns conditions. Comparedwith the water-splashing noise of the field test, the average difference of the theoretical and the measured value is 0.82 dB, which validates the accuracy of the established theoretical model. The results based on theoretical model showed that, when the water droplet diameters are smaller in cooling tower, the attenuation of total sound pressure level of the water-splashing noise is greater. From 0 m to 8 m away from the cooling tower, the sound pressure level of the watersplashing noise of 3 mm and 6 mm water droplets decreases by 8.20 dB and 4.36 dB, respectively. Additionally, when the water-spraying density becomes twice of the designed value, the sound pressure level of water-splashing noise all increases by 3.01 dB for the cooling towers of 300 MW, 600 MW and 1000 MW units. Finally, under the partition water distribution patterns, the change of the sound pressure level is small. For the R s/2 and Rs/3 partition radius (Rs is the radius of water-spraying area), when the water-spraying density ratio between the outer and inner zone increases from 1 to 3, the sound pressure level of water-splashing noise increases by 0.7 dB and 0.3 dB, respectively.
