Effect of Helix Angle of Spirally Corrugated Tube on Condensation Heat Transfer Characteristics

摘要

Spirally corrugated tubes with different helix angles have been used in experiments on the characteristics of condensation heat transfer and flow resistance. The result of the experimentation shows that the helix angle plays a vital part in the spirally corrugated lube during the process of condensation heat transfer. This paper analyzes the mechanism of how the helix angle influences the characteristics of condensation heal transfer and flow resistance, and presents an experimental correlation formula of condensation heat transfer which takes the helix angle into account as a factor.
