摘　　要：采用计算流体力学方法,数值模拟研究了四种弧形滤毒罐气动特性。采用三维纳维-斯托克斯(NavierStokes)方程和低雷诺数修正k-ε湍流模型求解,主要分析了不同气流流量下四种弧形罐的通气阻力、内部流场结构,并与目前国内常用圆柱形滤毒罐模型A的气动特性进行比较。研究结果表明,双面弧形结构滤毒罐的通气阻力最小,且气流分布较均匀。导流槽设计使得滤毒罐通气阻力减小,对吸附层气流分布影响较大,不能抑制吸附层中间高速气流,使得气体快速通过吸附层。The computational fluid dynamic(CFD)method was used to study the aerodynamic characteristics of four arc canister.The three-dimensional Navier-Stokes equation and low Reynolds number correction k-εturbulence model were employed.The pressure drop and inner flow structure of four arc canister under different flow rates were analyzed.The aerodynamic characteristics of the arc canisters were compared with the aerodynamic characteristics of the current domestic commonly used canister.The results show that the canister withdouble-sided arc-shaped structure has lowest pressure drop and most uniform air flow distribution.The channel design can reduces the pressure drop of the canister.It cannot suppress the middle high speed air flow of the adsorbent layer,so that the gas can pass through the adsorbent layer quickly.
