摘要

通过对水平管内饱和纯蒸汽强制对流冷凝换热的实验研究

分析在管内两相流型为环状流-半环状与波状流时

质量含汽率、蒸汽入口流速和压力对蒸汽冷凝换热的影响

并得到了同时适用于这两种流型的计算局部冷凝传热系数的经验关联式。结果表明:局部冷凝传热系数在环状流-半环状流及波状流下均随质量含汽率和压力的降低而减小;在环状流-半环状流下

随蒸汽入口流速的升高而增大

在波状流下

随蒸汽入口流速的增大而减小;实验拟合所得到的换热经验关联式与实验结果符合良好

偏差在±20%以内。

Abstract

An experimental investigation on forced convection condensation of saturated steam inside a horizontal tube was performed. The influences of steam quality

inlet steam velocity

and inlet steam pressure on condensation heat transfer were analyzed for annular-semiannular and wavy flows. A correlation for the local heat transfer coefficient of saturated steam condensation along a horizontal tube for both annular-semiannular and wavy flows was developed. For both annular-semiannular and wavy flows

local heat transfer coefficient decreased with steam quality and steam pressure. However

local heat transfer coefficient increased with inlet steam velocity for annular-semiannular flow while decreased with inlet steam velocity for wavy flow. The new correlation showed good agreement with experimental results with an error of 20% between calculated and experimental results.
