Leidenfrost temperature increase for impacting droplets on carbon-nanofiber surfaces [PDF]

open access: yes, 2013
Droplets impacting on a superheated surface can either exhibit a contact boiling regime, in which they make direct contact with the surface and boil violently, or a film boiling regime, in which they remain separated from the surface by their own vapor ...

An experimental approach to heat loss measurement of horizontal two-phase flow boiling in low-pressure low-flow (LPLF) conditions

open access: yesCase Studies in Thermal Engineering
A crucial parameter remarkably influencing the reliability and accuracy of vapor quality measurements in flow boiling experiments is the measurement of heat loss.

Flow in fuel nozzles under cavitation and flash-boiling conditions

open access: yesAIP Advances, 2022
Cavitation plays a crucial role in various fuel systems and spray applications. Due to the limitation in experimentally measuring the cavitation flow in fuel nozzles, numerical simulations can be used as an alternative in exploring the underlying physics.

Modeling and Simulation Analysis on Mixing Characteristics of Two-Phase Flow Around Spacer Grid

open access: yesFrontiers in Energy Research, 2022
The spacer grid has a significant impact on the thermal-hydraulic characteristics of the rod bundle channel, which directly determines the possibility of a boiling crisis.

Pressure drop across micro-pin heat sinks under boiling conditions [PDF]

open access: yes, 2009
Two-phase pressure drop was studied in four different micro pin fin heat sinks. Micro pin fin heat sinks used in the current studies were operated under boiling conditions using water and R-123 as working fluids.

Thermohydrodynamics of boiling in a van der Waals fluid [PDF]

open access: yes, 2012
We present a modeling approach that enables numerical simulations of a boiling Van der Waals fluid based on the diffuse interface description. A boundary condition is implemented that allows in and out flux of mass at constant external pressure.

Multiple ETS family transcription factors bind mutant p53 via distinct interaction regions

open access: yesFEBS Letters, EarlyView.
Mutant p53 gain‐of‐function is thought to be mediated by interaction with other transcription factors. We identify multiple ETS transcription factors that can bind mutant p53 and found that this interaction can be promoted by a PXXPP motif. ETS proteins that strongly bound mutant p53 were upregulated in ovarian cancer compared to ETS proteins that ...

Pressure Drop of HFE7000 and HFE7100 in Flow Condensation in Minichannels With Account of Non-Adiabatic Effects

open access: yesMATEC Web of Conferences, 2014
Flow boiling and flow condensation are often regarded as two opposite or symmetrical phenomena involving the change of phase. There is a temptation to describe both these phenomena with one only correlation.

Similarities and differences between flow boiling in microchannels and pool boiling [PDF]

open access: yes, 2009
This paper was presented at the 2nd Micro and Nano Flows Conference (MNF2009), which was held at Brunel University, West London, UK. The conference was organised by Brunel University and supported by the Institution of Mechanical Engineers, IPEM, the ...
