Abstract
Problem Statement: This article describes a laboratory installation designed by the Department of Theory and Automation of Metallurgical Processes and Furnaces of the North Caucasian Institute of Mining and Metallurgy (the State Technological University). The article also describes how the installation functions and the research procedure applied. Objectives: This work aims to improve laboratory equipment to provide a visual representation of heat transfer processes. Originality: In comparison with its counterparts, this installation can help obtain a great number of thermal parameters which are necessary for studying and modeling of heat transfer processes. Findings: The developed unit enables to study the heat transfer processes by way of simulation using a mathematical model based on the zonal method. Due to its design, the unit can be quickly re-adjusted to run in counter-flow mode instead of once-through mode. It has an automatic control and adjustment functionality. Practical Relevance: The unit gives an insight into heat transfer, heat flows and the heat exchange regularities, and it provides a practical guide which can be used for training highly qualified personnel.
