| 摘 要： | 船用蒸汽冷凝器是船舶动力系统的重要组成设备之一,其冷却水阻力计算是冷凝器热力计算的重要内容,相关参数的确定关系到设备设计的成败,也影响着船舶动力系统的性能.采用1:1比例全三维数值模型对冷凝器内冷却水的流动特性进行数值模拟,获得了冷凝器的流场运动规律和流阻特性,并与试验结果相比较,二者吻合较好.通过利用试验验证的数值计算方法,可为提高蒸汽冷凝器的冷凝效率,优化其结构设计提供技术支撑.

| Abstract: | Steam condenser is the one of the most important devices in the marine power system. The calculation of cooling water resistance is the main constitution of the steam condenser thermodynamics calculation. The definition of relative parameters not only affects the design of device, but also the performance of ship power system. Three-dimensional model is applied to simulate the flow characteristic of the cooling water in stream condenser. The skeleton map of three-dimensional flow was depicted distinctly. In... |
