Performance of the spraying cooling system as an EPR

Laboratory modeling and theoretical investigations of an abstract easily penetrable roughness, as well as the in-situ measurements overviewed in Section 1.4, were carried out to perform a real object, an extended spraying cooling system for a project of the Zaporizhzhya nuclear power plant shown in Fig. 1.12. The interpretation of its droplet layer as an EPR was done in Section 1.4. It is the aim of this section to briefly present the main results of a one-dimensional theory. 

From an engineering point of view, the spraying cooling system (SCS) is determined by two groups of factors. Environmental factors determined by meteorological measurements include 

Design factors that are of a major importance for engineers include 

The ratio of the water output to the irrigation area Aq = l2 is called the irrigation 

Recall that this theory is valid under only windy conditions. Under windless conditions, a special theoretical scheme should be developed, [211], The field experimental data given in Fig. 1.14 confirm that the droplet layer decelerate the wind like it happens in canopy. The first attempt to perform the SCS with an account of the air flow transformation through it was done by Chaturvedi and Porter [114]. Like here, they interpreted the SCS as a droplet layer that decelerates the flow and saturates it by heat and
