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.

研究的目的是了解 喉道壁和锥角的整体 在扩大的圆柱形密封腔中混合流动， 锥形机械密封 这项研究将带来根本性的成果 了解密封腔中的流动行为。 因此 基于这一认识，新的密封室设计， 预期密封面的整体冷却。 另外通过 追踪流中的塑料颗粒，密封室 形状将被优化，以减少磨料的侵蚀作用 颗粒物，减少泄漏，以控制污染。 因此，这 研究将有助于泵和机械的进步 密封制造技术，提供适当的手段， 增加这些产品的平均故障间隔时间。
