Engineering Case Histories: Case 100—Was sloshing the cause of a failure?

Some situations in failure analysis demand an understanding of the wave motion of a liquid wave in a tank, called “sloshing.”

Some situations in failure analysis demand an understanding of the wave motion of a liquid wave in a tank, called “sloshing.” Mixers agitating a product, tank trucks making sharp turns, ships carrying liquid products or a floating roof tank undergoing seismic activities are examples of sloshing. A case history was used as a preliminary investigation into why some internal components in a very large, complex, agitated processing tank were failing. Sloshing can be demonstrated by the sudden, side-to-side movement of a cup of coffee on a table, as shown in Fig. 1. The fluid will keep moving back and forth in a wave action after the cup motion has stopped. This is the liquid’s first-mode natura
