Methodology of Visualization of non-Isothermal Mixing Processes Under the Influence of External Dynamic Forces

Abstract

This article considers the problem of taking into account the influence of a change in spatial orientation on thermal-hydraulic processes. To obtain the parameters of non-isothermal mixing and create a database of these processes, first of all, an experimental method was used to study these processes on a small-scale model. The obtained parameters were visualized and further graphic images were analyzed using the OpenCV library (Open Source Computer Vision Library - an open source computer vision library). A new approach to visualization of mixing processes of non- isothermal flows is proposed. The result of this analysis was the integral and local characteristics of the process of non-isothermal mixing of flows. To assess the degree of influence of a change in the nature of the problem on the integral characteristics of the process of mixing of non-isothermal flows, a series of experiments was carried out for various types of problems. The research is limited by the scale of the model, and there is also a need to develop other criteria for assessing the nonisothermal mixing of flows under the influence of external forces. The value of the article is a new approach to the evaluation of non-isothermal mixing processes. The analysis of the obtained images makes it possible to study the process of non-stationary heat transfer under the conditions of external dynamic influences and to identify areas of non-uniform mixing.
