Based on that the film filling was simplified to the flat plate model, the heat and mass transfer of the filling zone with fouling in cooling tower were analyzed. The effect of fouling on the performance of filler was analyzed according to the dirt growth model. The work done in this paper can simply forecast changes in cooling tower performance caused by the filler fouling. It will lay a theoretical foundation for accurately calculating the performance coefficient of filler. And it is helpful to solving the problem of no the ripe empirical formula of filler performance with fouling for engineering applications.

This paper discusses heat and mass transfer in cooling tower fill. In this research, dry bulb temperature at the bottom fill, ambient relative humidity, air stream velocity entering fill, dry bulb temperature leaving the fill, relative humidity of air leaving the fill, inlet and outlet water temperature of cooling tower were measured. Those data used in heat and mass transfer calculation in cooling tower fill. Then, do the heat and mass transfer calculation based on proposed approch. The results are compared with design data. The design and analogy method showed different  result. The parameter which influence the heat transfer at cooling tower are represented by coefficient of heat transfer hl and coefficient of mass transfer k­l. The differencies result between design and analogy method shows that there is important parameter which different. Deeply study needed for it.

Aerodynamic Investigation

A new efficient ceramic regular sedimentation for heat and mass transfer in apparatuses of environmental protection is proposed. A new sedimentation realization with isotropic properties of a structure is offered. The aerodynamic test results of the new sedimentation are shown. The paper describes a laboratory test facility designed for conducting aerodynamic investigation of cooling tower sedimentation. Measured parameters, data processing techniques and examples of the results obtained are discussed. The tested sedimentation is a porous layer of ceramic foam manufactured by special technology.
