摘要:
为了降低汽车空气滤清器进气阻力,应用计算流体动力学方法建立壳体和滤芯的耦合数值计算模型.利用正交分析方法研究进出气口结构参数对进气阻力的影响规律,总结进气阻力随流量变化的关系式,通过滤芯的流量-压降实验验证数值计算方法的可靠性.结果表明:进气阻力随着流量的增加呈抛物线趋势增加;在额定流量工况下,进气阻力随着出气口面积的增加而减小,负载时最大降幅达到37.2%;进出气口圆角半径越大,进气阻力越小,负载时最大降幅分别达到16.6%和36.2%.
Abstract:
To reduce the air intake resistance of automotive air filter, a coupled numerical model of shell and filter element was established by using computational fluid dynamics technique. The influence of the inlet and outlet structure parameters on air intake resistance was analyzed by orthogonal analyses method, and the relationship between the air intake resistance and the mass flow rate was summarized. The reliability of the numerical calculation method is verified by the experiment of flow rate versus pressure drop in the filter element. The results showed that the air intake resistance increased at parabola trend with the increasing mass flow rate. Under rated flow conditions, the air intake resistance decreased with the increasing outlet area and the maximum drop was 37.2% under load conditions. The air intake resistance decreased with the increasing inlet and outlet fillet radius, the maximum drop was 16.6% and 36.2% under load conditions.
