recommendations! Published in 2021 at "Nuclear Engineering and Design"

DOI: 10.1016/j.nucengdes.2021.111185

Abstract: Abstract The two-fluid model has been adopted as a platform of nuclear thermal–hydraulic system analysis code because it can treat the mechanical and thermal non-equilibrium between phases through the interfacial transfer terms. Precise modeling of… read more here.

DOI: 10.1080/00223131.2019.1617203

Abstract: ABSTRACT Accurate prediction of interfacial drag in the downcomer annulus is crucial for the assessment of downcomer void fraction for the loss of coolant accident analysis. The downcomer annulus is the gap between reactor pressure… read more here.

DOI: 10.3390/fluids5010031

Abstract: The continuous adjoint approach is a technique for calculating the sensitivity of a flow to changes in input parameters, most commonly changes of geometry. Here we present for the first time the mathematical derivation of… read more here.

DOI: 10.37190/ppmp/178234

Abstract: This communication presents a methodology, based on a modified drift flux model, to determine bubble size distribution in column flotation. The modified drift flux model incorporates a surfactant-type parameter. This parameter considers the impact of… read more here.
