摘要
应用k ε双方程模型对内循环流化床锅炉炉内卧式旋涡分离器冷态气相进行了数值模拟。给出了分离器内速度矢量图 ,为减小数值伪扩散对强旋流动的影响 ,采用了减少网络尺寸等措施。
This paper adopts k ε two equations model,completes the horizontal vortices segregator numerical simulation of inter circulating fluidized bed boilers,and the relative vectors are carried out.To reduce the influence of the numerical diffusion on the computational results,such as decreasing the grid size has been used.The simulation results obtained enhance our understanding of the flow and help the separator in the design and improvement.
