Analysis and optimization of exergy losses in a heavy water distillation column
Abstract: Heavy water (D2O) of isotopic purity 99.9% and more is used as the moderator and the coolant in pressurized heavy water nuclear reactors (PHWRs). This purity is maintained by vacuum distillation. In the column there are various sources of irreversibility and thermodynamic inefficiency. This work presents an analysis of these losses in a typical heavy water distillation column and their dependence on various design and operating parameters of the column. …

A Review: Performance analysis of overlapping shear keys in box girder bridges using finite element based software
Abstract: Abstract - Box girder bridges are widely used for long-span constructions due to their high strength-to-weight ratio and structural efficiency. A fundamental component in these bridges is the shear key which allows for effective transfer of loads between bridge segments and upholds the overall structural performance through the different load cases. Overlapping shear keys are becoming increasingly popular because they greatly enhance inter-segment connections, which decrease relative displacements. This paper …
