Visualization of Non-Isothermal Liquids Mixing Processes Under the Influence of External Forces

Abstract

The paper presents a visualization of the mixing processes of non-isothermal flows in the model of a ship's nuclear power plant under static and dynamic modes. The values obtained at the experimental stand served as the database for visualization. It is a four-loop model of the flow part of a ship's nuclear power plant. To create a dynamic mode (oscillations in one plane), the model is placed on a swinging platform. This paper shows the processes occurring during periodic pitching with a period of 4 seconds and amplitude of 15 degrees. The descending annular section of the circulation tract was chosen as the object of research. Then the resulting database was visualized using the 3DFieldPro program, where a color scale was matched to the temperature data and model coordinates, and also with the help of the OpenCV library with a high-level implementation program С++, the characteristic hot/cold vortices (spots), the boundary of the mixing process, its character in static mode (without fluctuations) and dynamic mode were analyzed. The uneven mixing process was noted, especially in the dynamic mode. The resulting tools allow you to quickly and clearly visualize these processes.
