The paper presents a research on the heat-transfer coefficient at the surface of a sprinkled tube bundle, using a boiling simulation. A tube bundle consists of thirteen copper tubes divided into two rows and it is located in a low-pressure chamber where vacuum is generated by an exhauster via an ejector. The liquid tested was water at the absolute pressure in the chamber of 96.8–12.3 kPa and at a thermal gradient of 55–30 °C between the cooled liquid flowing upwards inside the exchanger and the heated falling film liquid. The flow of the falling film liquid ranged from 0–17 L/min. Two types of tubes were tested, a smooth one and a sandblasted one. The correlation of the average heat-transfer coefficient at the surfaces of both tube types was identified.
