What is it about?
In this study, in order to increase the heat transfer rate in a spiral-coil tube by an active method, a rotating ball valve was mounted downstream/upstream of the spiral-coil tube and used as a pulse generator. Influence of pulsation on heat transfer in the spiral-coil tube was experimentally investigated.

Why is it important?
Efficiency of spiral-coil heat exchangers will be increased.
Perspectives
Improvement of applications of coiled tubes such as helical and spiral coils are used widely in variety of heat exchangers, such as storage tanks, chemical reactors, agitated vessels, food processing, dairy industries, refrigeration, and air conditioning systems.
