... Abstract The accurate prediction of critical heat flux (CHF) is of great significance to the safe operation of the reactor. At present, most of the traditional methods for predicting CHF are based on relational fitting in mathematical form, which are not accurate enough and may can not taking...

... pressure vessel lower head is in the pool boiling state. In this research a one-dimensional full-height experimental facility was established to research the heat transfer limit (CHF) of ERVC under the pool boiling condition with a one-dimensional heating block, which is used to simulate the lower head...

... Abstract Safety is the biggest concern of nuclear power plant and research reactors.As one of the three primary thermal design criteria for rectors, the critical heat flux (CHF) guarantee the reactor’s safety and economics. The bubble dynamics in narrow rectangular channel is didderent from...

... boiling (DNB) occurs, the prohibited. Other names may be trademarks of their respective owners. critical heat flux (CHF) must be accurately determined for In this paper, the new methodology is described for local different conditions in order to maintain reasonable margin to resistivity measurement...

... Abstract In-Vessel Retention (IVR) strategy is one of the most important severe accidents mitigation strategies. The Critical Heat Flux (CHF) is an important key element in the assessment of IVR efficiency. How to increase the CHF is a significant method to make sure the IVR success. Heating...

... Abstract Heat transfer between cladding and coolant during transient scenarios remains a critical area of uncertainty in understanding nuclear reactor safety. To advance the understanding of transient and accident scenarios involving critical heat flux (CHF), an in-pile experiment...

... 05 03 2009 An experimental study of the critical heat flux (CHF) and the associated limiting critical quality phenomenon has been conducted recently for horizontal and vertical tubes cooled with water and the refrigerant R-134a. The objective of this study is to compare the CHF...

... 05 03 2009 For the purpose of predicting CHF for a wide range in quality, we developed the analytical CHF prediction method. Two-phase flow analysis code based on multi-fluid model was developed and, by using typical dryout model and DNB model, CHF predictions for a wide range...
