The present version of the Pressure Vessel Standard, BS 5500’ restricts the design of the local load type situations to certain vessel and attachment geometries. This paper identifies the main underlying reasons for these restrictions; which are a limitation of the deflection and rotations by the use of small displacement analysis, and a neglect of the rigidity of the attachment. This paper add...

This paper deals with model-based pressure and flow control of a fine coal injection vessel for the use of the blast furnace injection process. By means of system modeling aild identification, the structure and behavior of the coal injection vessel are analyzed. It is shown that by use of model-based design, the control goals can be reached and the control performance can be significantly impro...

The breeder thermal performances under a purge line break have been analyzed for two blanket design options: a blanket design using a packed breeder bed and a blanket design using a sintered breeder product. Under a purge line break open to a vacuum environment, the packed bed breeder temperature exceeds its operating temperature limit at a faster rate than that of the sintered breeder blanket ...

Compliance mismatch, thrombosis, and long culture times in vitro remain important challenges to the clinical implementation of a tissue-engineered small-diameter blood vessel (SDBV). To address these issues, we are developing an implantable elastomeric and biodegradable biphasic tubular scaffold. The scaffold design uses connected nonporous and porous phases as a basis to mimic, respectively, t...
