Highlights

?The entire CIWH process was captured and its pressure fluctuation was analyzed.

?A CIWH region map including three types of CIWHs was proposed.

?Generation frequency of CIWH decreased with steam mass flux and water temperature.

?A dimensionless correlation was obtained to predict Strouhal number.

Abstract

The condensation induced water hammer (CIWH) phenomenon may cause serious damage to the pipes and related system, which often occurs during the steam-water direct contact condensation process. In this paper, an experimental investigation was performed to study CIWH phenomenon caused by steam-water direct contact condensation in a horizontal pipe. The entire CIWH process was captured by a high speed video camera and its pressure fluctuation was synchronously measured. Four typical flow patterns were observed during CIWH process: stratification flow, wave flow, slug flow and bubble collapse. Bubble collapse w

抽象

冷凝诱导的水锤（CIWH）现象可能对管道和相关系统造成严重损坏，这通常发生在蒸汽 - 水直接接触冷凝过程中。本文进行了实验研究，以研究水平管中蒸汽 - 水直接接触凝结引起的CIWH现象。通过高速摄像机捕获整个CIWH过程，其压力波动同步测量。在CIWH过程中观察到四种典型的流动模式：分层流动，波流，裂片流和泡沫塌陷。泡泡崩溃W.
