Effect of fill length and distribution system on the thermal performance of an inverted cooling tower

In the design of a cooling tower there are two key aspects, the thermal performance and emissions level. The main objective of this paper was the experimental optimisation in terms of thermal performance of a new prototype of the forced, mechanical-draft, wet, inverted cooling tower. In this sense,...
