摘要
应用有限体积法,借助FLUENT分析了突然收缩和突然扩张型固定节流阀在节流孔孔径为14 mm时的流场特性,揭示了流线、速度、压力分布,讨论了节流孔长度、孔径对压降的影响。提出了一种新型节流阀结构,可有效增大压降,为固定节流阀结构优化及性能改善提供参考依据。
Using finite volume method, the flow field characteristic was carried on the fixed throttle which is sudden contraction and sudden expands with the aid of FLUENT when the throttle aperture is 14mm. It has promulgated the distribution of the flown line, speed, pressure. And the influences of pressure drop by the length of bore, the aperture are discussed. One kind of new throttle structure was proposed. After the analysis indicated that it may increase the pressure drop effectively, which offer the reference to the optimal design of structure and performance improvement of the fixed throttle.
