摘要： 为解决海洋温差能发电中换热器的计算问题,基于MATLAB软件,提出一种应用于海洋温差能发电(ocean thermal energy conversion, OTEC)满液式换热器沸腾传热与凝结传热的传热计算方法,并建立海洋温差能满液式换热器数学模型。在此模型的基础上,针对表层25~30 ℃温海水、深层4~6 ℃冷海水的OTEC循环工况,分析不同循环工况下换热器传热系数的变化情况;针对进水温度、进水流量、壳程压力对换热效率的影响进行数值计算,得出OTEC循环工况下不同因素对满液式换热器传热系数的影响。研究表明,OTEC循环工况下蒸发器传热系数与温海水的进水温度、流量、壳程压力呈正相关;冷凝器传热系数与冷海水的流量呈正相关,与进水温度、壳程压力呈负相关。通过海洋温差循环试验平台进行试验,将试验结果与数学模型相对比,验证了数学模型的准确性。
