... conservation, the new version of the program includes correlations for calculating heat transfer and friction resistance, taking into account the strong dependence of the properties of the coolant on temperature and pressure. In particular, the use of the universal calculation model of heat transfer, developed...

This paper presents simulation results of the in-pile Bain Fondu (BF1) test, performed within the SCARABEE-N program, using accident source term evaluation code (ASTEC), Sn method implicit multifiel multiphase Eulerien...

...Dong Yang; Jiaxiang Chen; Yongchang Feng; Lin Chen Thermal efficiency and safety of generation-IV nuclear-power-reactor concept supercritical water-cooled reactor (SCWR) are largely dependent on the coupled supercritical water (SCW) thermophysical properties and heat transfer performance...

...V. I. Deev; V. S. Kharitonov; A. M. Baisov; A. N. Churkin The paper contains the results of analysis of heat transfer regimes in the case of forced turbulent flow of water and modeling fluids in channels of various configurations at supercritical pressures. Two new complex criteria were proposed...

...-to-diameter (P/D) ratio. This includes the maximum fuel temperature, critical heat flux, as well as pressure drop through the fuel bundle. An understanding of the detailed structure of flow mixing and heat transfer in a fuel rod bundle geometry is therefore an important aspect of reactor core design, both...

..., h r (W/m 2 K), is conservatively considered negligible due to the low absolute temperatures in the target. The gas gap conductance, the primary form of heat transfer for the preliminary targets [ 1 ], shares its contribution with the contact conductance (detailed in Sec. 2.3 .) (5) h = h...

...Aleksei Chernysh; Mikhail Iarmonov; Kirill Makhov; Aleksandr Beznosov The process of heat transfer in a heavy liquid-metal coolant (HLMC) cross-flow around heat-transfer tubes has not been thoroughly studied yet. Therefore, it is of great interest to carry out experimental studies for determining...

...Sandeep R. Pidaparti; Jacob A. McFarland; Mark M. Mikhaeil; Mark H. Anderson; Devesh Ranjan Experiments were performed to investigate the effects of buoyancy on heat transfer characteristics of supercritical carbon dioxide in heating mode. Turbulent flows with Reynolds numbers up to 60,000...
