... studied. A more accurate three-dimensional model was also developed by considering the conduction–convection cooling mechanism coupled with radiation, and the effect of the number of supercontainers was studied in more detail, as well as a bounding case with zero heat flux at both ends. The modeling...

... progressing along the circumferential weld path around the intersection during each pass. The effect of cooling rate on the final residual stress state, especially at critical areas where the peak residual stresses are located, was then investigated by applying different convective heat transfer coefficients...

... of emergency core cooling was performed, and the leading leak size was determined. A fracture mechanics based assessment was carried out for extended circumferential flaws in the weld joint between the RPV shell and the flange, as well as for axial flaws in the nozzle corner. These flaw geometries postulated...

... of in-service welding, the results are compared with those of a no-flow case. It is found that the flowing media took away most of the heat effects from welding. The cooling is accelerated and the peak temperature of the inner surface of the pipe is much lower than that of the no-flow case. An experiment...

...Mark Bass; Rolf R. de Swardt A 155 mm compound gun barrel with full-length integral mid-wall cooling channels was manufactured and connected to a purpose built heat exchanger. Laboratory testing of this system was carried out using electrical heating jackets applied to the outer surface...

... cooled compound gun tube where a loose-fitting inner tube (liner) is permanently deformed by means of hydraulic pressure to lock it to the outer tube (sleeve). The interaction between the liner and sleeve was modeled with contact elements. The effect of machining subsequent to the hydraulic autofrettage...

According to the numerical and experimental study, the sufficiently useful results are proposed to realize the further development and high performance of a type of cryogenic two-phase cooling system. It is numerically and experimentally found that the inception...

...Hiroshi Nagakura; Shigehiko Kaneko This paper presents an analytical model for the self-excited sloshing due to the fluid discharge over a flexible weir, as observed in the cooling circuit of the French fast breeder reactor, Super-Phenix-1. To clarify the instability mechanism, we analyzed the case...
