Abstract

A two-phase bubbly flow mixing device and method at the bottom inlet of a vertical rod bundle channel. The auxiliary water inlet area composed of the auxiliary water inlet chamber, the filter element structure composed of the filter element circular tube section, the filter element transition section and the filter element porous section, and the device consisting of the upper and lower pipe seats of the device, the filter element casing, the filter element fixing plate and the filter element casing fixing plate Support and fixed structure; after the gas enters from the round pipe section of the filter element, it flows out from the porous section of the filter element through the transition section of the filter element and mixes with the auxiliary water inlet to flow upward. The gas-liquid two-phase formed by mixing is then mixed with the main water inlet. Obtain bubbly two-phase flow with different gas content, and finally enter the rod bundle channel area; the present invention can obtain a larger range of bubbly two-phase flow, satisfying the two-phase bubbly flow for different vapor content in the rod bundle channel Experimental requirements; in addition, the present invention also has the advantages of simple operation, high stability, and easy processing and installation of the device.

Description

technical field

[0001] The invention belongs to the technical field of two-phase bubbly flow experiment research, and in particular relates to a two-phase bubbly flow mixing device and method at the bottom inlet of a vertical rod bundle channel. Background technique

[0002] Gas-liquid two-phase flow is widely used in industries such as petroleum, chemical industry, energy, power, aerospace systems, and pharmaceuticals. It usually contains complex and variable flow patterns, including bubbly flow, slug flow, annular flow, and mist flow. etc. It is of great significance to study its flow pattern characteristics in the production process and scientific research.

[0003] In the experimental research of gas-liquid two-phase bubbly flow, the first problem to be solved is the formation of bubbly flow and the mixing of gas-liquid two-phase. The usual method is to add special equipment for gas-liquid mixing on the gas-liquid two-phase flow circuit. , but due to the complexity of g...
