축열식 버너의 전환을 고려한 가열로 내부 열유동에 관한 수치적 연구

초록

In this study, the effects of regenerative burner switching operation on the thermo-fluid characteristics inside a reheating furnace are numerically investigated using ANSYS Fluent. The combustion process is modeled with the Finite-Rate/Eddy-Dissipation (FR/ED) model, while radiative heat transfer is handled by the Discrete Ordinates (DO) model. The numerical model is first validated against benchmark data from previous studies to ensure its reliability. Subsequently, a parametric study is conducted to investigate the influence of stored heat variation and periodic burner switching on the internal thermo-fluid field. The results elucidate how these parameters affect flow and temperature distributions within the furnace and determine the characteristic time required for the system to reach a periodic steady state.
