Our C. T. Design is based on heat transfer from water drops to the surrounding air by the transfer of sensible and latent heat. Sensible heat transfer owing to difference in temperature of water and air. Latent heat transfer owing to vaporization of small portion of water.
To achieve this , whirljet nozzles are used. Due to water jet partial vaccum is created on top of the tower which induces surrounding air from top to bottom, (co-current) which in turn cools the water. For better surface contact atomisation (Mist formation) of water is created.
