Industry Internship: Experimental Investigation of Flow Behavior in Mechanical Seal Chambers Using Laser Doppler Velocimetry Technique

研究的目的是了解喉部壁厚和锥角对圆柱形和锥形机械密封密封腔内流体整体混合的影响。这项研究将有助于从根本上理解密封室内的流动行为。作为这一理解的结果，新的密封室设计有望改善密封面的整体冷却。此外，通过跟踪流动中播撒的塑料颗粒，将优化密封室的形状，以减少磨料颗粒的侵蚀影响，减少泄漏，以控制污染。因此，这项研究将有助于泵和机械密封制造技术的进步，为延长这些产品的平均故障间隔时间提供适当的手段。

The objective of the research is to understand the effects of the throat wall and angle of taper on the overall mixing of flow in the seal chamber of enlarged cylindrical and tapered mechanical seals. This research will lead to fundamental understanding of flow behavior in the seal chambers. As a result of this understanding, new seal chamber design for improved overall cooling of the seal faces is expected. In addition, by tracing plastic particles seeded in the flow, the seal chamber shape will be optimized to reduce the erosive effects of abrasive particles and reduce leakage for pollution control. Thus, this research will contribute to advancement of pump and mechanical seal manufacturing technology by providing appropriate means to increase the mean time between failures for these products.
