ABSTRACT

The paper develops an approach for the effective analysis for air washer. The approach can be used for the simultaneous heat and mass transfer in air washers operating as evaporative coolers. By using proper computational technique, the solution has been obtained for the above air washer. The solution gave an excellent match with the results available in the literature. The performance study of the air washer was carried out by varying several essential parameters such as inlet humidity ratio, airflow rate, water inlet temperature, and inlet air dry bulb temperature. The variation of outlet air temperature with respect to water inlet temperature was investigated under different inlet humidity ratio, mass ratio, inlet dry bulb temperature, and length of air washer. It was observed that the efficacy of air washer will increase by reducing inlet water temperature air flow rate and inlet humidity ratio. Further, the results show that the effect of inlet water temperature on the air outlet temperature is more for larger air washer length. The effect of spray ratio on outlet air temperature decreases as the water inlet temperature increases and this effect becomes zero at a particular inlet water temperature.
