Fast Calculation of Transient Thermal Stress in Surge Lines with Thermal Stratification Region
نویسندگان
چکیده
Nuclear power plants applying for license renewal are required to undertake a fatigue assessment of various components, which demands the fast calculation transient thermal stress fatigue-sensitive components such as surge lines. In this study, strategy Green’s function database construction stratification region was investigated, and shown be more accurate by dividing flow cases zones. Furthermore, method determine fluid temperature zones studied. addition hot leg outlet from pressurizer, seven thermocouples installed on outside wall in were used with stratification, result verified functions.

15 صفحه اولVariability of Thermal Stratification in Naturally Ventilated
Building energy simulation programs often use standard thermal comfort indices and thresholds as boundary conditions. However, most of them focus on comfortable indoor hydrothermal levels, rather than spatial distributions. This paper investigates internal temperature vertical stratification in naturally ventilated residential buildings. To evaluate this effect, a field study was carried out in...
متن کاملTILTS: A Fast Architectural-Level Transient Thermal Simulation Method
As power density of microprocessors is increasing rapidly and resulting in high temperatures, the reliability of chips is greatly affected, making thermal simulation a necessity for CPU designs. Current thermal simulation methods (for example, the HotSpot simulator) are very useful, but are still inefficient when performing thermal analysis for long simulation times. In this paper, we propose a...
