Study on Numerical Simulation for Pressure Drop in Diesel Engine Metal Mesh Filter Element
Author(s): 
Pages: 24-27
Year: Issue:  10
Journal: Hydraulics Pneumatics & Seals

Keyword:  微粒捕集器金属丝网压降数值模拟;
Abstract: 分析两种典型金属丝网滤芯的物理模型,依据Darcy-Forchheimer定律,建立金属丝网压降计算的数学模型,通过实验法确定模型中渗透率和惯性系数两个参数值.采用计算流体动力学(CFD)软件FLUENT对回形和柱形滤芯进行了数值模拟,验证得出所建模型适用于丝网滤器压降的数值模拟.研究结果为采用工程仿生学原理并进一步研究仿生耦合不粘滤器提供了理论分析基础.
