TL;DR: In this article, a new single-phase convective heat transfer augmentation correlation has been developed using single phase steam cooling experimental data obtained from the Penn State/NRC Rod Bundle Heat Transfer (RBHT) facility.

TL;DR: In this article, an experimental version of TRACE is developed to estimate the interfacial area concentration (ai), which includes mechanistic models for bubble coalescence and disintegration, and it is found that the non-linear developments observed in the experimental data, which reflect bubble interactions, are predicted well using the IATE.

TL;DR: In this article, a two-phase dispersed droplet flow investigation of the grid-enhanced heat transfer augmentation has been done using steam cooling with droplet injection experimental data obtained from the Penn State/NRC Rod Bundle Heat Transfer (RBHT) facility.

TL;DR: In this paper, the authors performed scaled separate effects experiments to investigate the gravity-driven ingress of air into a helium filled vessel and found that the air-ingress transient is characterized by three distinct stages, namely: (a) the initial stage where the exchange flow rate linearly increases with time until it reaches its maxima and makes a transition; (b) the intermediate stage when the exchangeflow rate decreases from its maximum value and varies non-linearly with time; and (c) the final stage of ingress where exchange rate decreases asymptotically to
