【Abstract】 The characteristics of falling film evaporation are narrated in this paper. Based on mechanism of heat transfer, the structure specialty and heat transfer characteristic of corrugated tube are analyzed. Under certain experimental condition, the experimental research of condensing glucose solution in the corrugated tube is carried on and a heat transfer correlation in turbulent flow regime is obtained, which is expected to offer the basis for improvement and design of falling film evaporation.更多还原
