Development of sustainable system based on the high temperature process

研究の背景 Background


Metal production process such as an iron and steel production is a high temperature process which consumes a lot of energy. To achieve the sustainable society, not only improvement and optimization of each process, but also utilizations of waste heat and by-products emitted from a process to the other industries are promising. Exergy analysis is important because exergy can evaluate the quality of energy and substance.

研究の目標 Outcome


To investigate the material and thermal flows and the mechanism of reaction, we develop a multiphase simulator by using CFD, DEM, and MPS method. High temperature experiment is also carried out for evaluating the developed simulator. The material and energy flow in each industry and each processes are analyzed for optimizing the total system by industrial collaboration.
