Experiment System Of OTEC And Performance Research Of Plate-fin Condenser

This paper based on the heat-transfer and,flow theory of the plate-fin heatexchanger and two phase flow theory, have set up the OTEC experimental system andthe mathematics model of the plate-fin condenser , and the model is divided into thetwo-phase district and subcooling district according to the actual conditions. In thetwo-phase district , have supplemented the thermal balance equation of the heatexchanger and the equation founded on the liquid-vapor interface of the ammonia side,thus make the equation group sealed and can be solved, Furthermore, solve to it.bythe calculating software Matlab. Allow one heat exchanger as the research object,which is a self-same heatexchanger as condenser in the water side path, design and put up the laboratory bench,carry on measurement to flow of cold and hot both sides and difference in temperatureof imports and exports of the heat exchanger. consequently , fit the heat convectionrelated type of the condenser's water side according to the experimental data. The paper designs overally OTEC experimental system and confirms thecirculation form of the experiment . Moreover,Carries on the structural design orequipment selecting type in making up the part. Designs the overall procedure andinstallation diagram , and puts up the laboratory bench according to the drawing. Generally the research of relevant respects in the foreign.as the patentachievement , the research of this text has a certain meaning to the operation of theplate-fin condenser.
