【Abstract】 A general numerical computing program for three-dimensional and time-dependent fluid flow in an arbitrary lagrangian-eulerian scheme with the finite volume method was developed.The distribution of cold flow field in the reheating furnace with multi-rotating-plane flame burners was simulated and calculated.In order to optimize the fluid flow,the design of multi-rotating-plane flame burners was modified.The experimental results show that fluid flow in the furnace with burners optimized are more reasonable and it is advised to adapted burners optimized.更多还原
