摘要 运用Fluent6.3中的欧拉-欧拉模型模拟传统流化床与锯齿形波脉动进气流化床的运动特性,并进行对比,针对沿床高的气泡高度、当量直径及内压等因素进行分析,得出脉动锯齿形波进气流化效果比传统流化效果明显提高。 The operation characteristics of the traditional fluidized beds and the saw-shaped wave pulsed inflow fluidized beds were simulated using Euler-Euler model in characteristics was made. Some analyses were conducted of the diameter, and internal pressure of bubbles, it was concluded th Fluent bubble 6.3, height at the efficienc and a comparison between their along the bed height, equivalent y of the saw-shaped wave pulsed inflow fluidized beds was greatly higher than that of the traditional fluidized beds.
