Abstract
This paper presents the current research on heat transfer at a sprinkled tube bundle consisting of smooth tubes and located in a chamber inside of which a low pressure is created by an exhauster. It also monitors the changes of the heat transfer coefficient in relation to the speed of sprinkled and sprinkling liquid flow, thermal gradient and low pressure inside the chamber. This articles shows and compares extensive measurements in condensation and evaporation modes.
