Experimental Investigation on Coating Surface on the Convection-condensation Heat Transfer of Hot Humidity Air
摘要
Abstract
A modified surface of heat pipe was prepared with n-octadecyl mercaptan self-assembled monolayers (SAMs). In order to investigate the characteristics of convection-condensation heat transfer of the heat pipe heat exchanger and heat transfer enhancement after modification, vapor-air mixture generated by a boiler was used to simulate the flue gas experimentally. The experiment focused on factors that may affect the performance of the convection-condensation heat transfer and the efficiency of heat transfer enhancement in the presence of SAMs. The experiment was conducted under the condition of temperature ranged from 70 "C to 120 °C and of vapor volume fraction ranged from 0 to 20%. The results are shown below: the vapor volume fraction, the mass flow rate and the inlet temperature of the vapor-air mixture are the main factors that influence the performance of the convection-condensation heat transfer; the surface of heat pipe modified with SAMs has a great effect on the enhancement of heat transfer.关键词
