Computational fluid dynamics and turbulence model uncertainty quantification for nuclear reactor safety applications
… quantified in order to be useful in support of reactor licensing and decision making. In traditional system thermal hydraulics codes, the code scaling, applicability, and uncertainty (CSAU) approach is used to ensure simulation quality and to estimate the level of uncertainty present. No such …

Transient flow boiling CHF under exponentially escalating heat inputs
… accidents (RIAs) are a potential concern for nuclear reactor safety. In RIA scenarios, following the insertion of positive reactivity, e.g. by an unanticipated extraction of the control rods, the reactor power may increase exponentially. The period of the exponential rise, τ, depends on the …

Measurement of Liquid Film in Annular Flow Using X-Ray Densitometry
… flow film thickness is a crucial parameter in nuclear thermal hydraulics, yet conventional measurement techniques such as impedance probes may compromise accuracy by directly contacting and potentially disturbing the flow. Non-intrusive measurement methods are needed to provide more reliable …

Three-Phase and Unidirectional Heat Transfer
… thermal management would be in firefighting and nuclear reactor safety. Above a critical temperature referred to as the ``Leidenfrost temperature'', the highly effective nucleate boiling is completely replaced by insulating film boiling, causing a dramatic decrease in the essential cooling rate …
