Concentric arrays

Fluid elastic instability is the most important mechanisms that excite vibration of tube bundles in heat exchangers. The study on fluid elastic instability of concentrically distributed tube bundles can provide valuable guidance for the design, …

Concentric arrays of tube bundles are applied extensively in heat exchangers at nuclear power plants. Flow induced vibration is one of the main causes of heat exchanger failures. However, there is no corresponding standard and basic parameters in the …
