| Abstract: | A mathematical model of the velocity field for a regenerate reheating furnace was established with the commercial software CFX. Using the k-e turbulent model, the influence of nozzles' shape, size and distribution on the velocity field was studied. The results show that the flow pattern in the furnace is greatly different from that of a traditional furnace and is advantageous to the mixing of fuel and air. The shape of the furnace and especially the size and the site of nozzles influence the flow pattern to some extent. |
