Thermal performance and emissions analysis of a new cooling tower prototype

The design of a wet cooling tower involves a number of trade-offs including the efficiency of the device to remove waste heat (thermal performance) and environmental aspects (emissions level). This paper deals with the experimental characterisation of a new cooling tower prototype. The novelty of th...
