Growth and collapse of vapour bubbles in convective subcooled boiling of water
… and collapse of vapour bubbles during convective subcooled nucleate boiling of water in an internally heated annular test section was visualized using the high speed filming technique. The experiments were performed at atmospheric pressure, mean flow velocities of 0.08-0.8 m/s, liquid bulk …

Numerical study of vertical subcooled boiling flow with new wall nucleation models
Correct modeling of subcooled boiling flow has generated significant interest considering its use in a large number of industrial applications, including nuclear power plants. Due to the decrease in computational cost and the limitations of experimental studies, CFD simulation is a proven, powerful …

Study of Surface Tension, Natural Evaporation, and Subcooled Boiling Evaporation of Aqueous Surfactant Solutions
… evaporation under natural convection and subcooled pool boiling is examined through experimental methods. Aqueous solutions of sodium lauryl sulfate (SLS), ECOSURFTM EH-14, and ECOSURFTM SA-9 are used in this study. SLS is an anionic surfactant while EH-14 and SA-9 are …

Design and Construction of a Subcooled Boiling Flow Loop with an Internally Heated Vertical Annulus for Use in Testing Departure from Nucleate Boiling (DNB)
… design and testing of an apparatus to use in subcooled boiling flow experiments. A vertical annulus flow loop was design to mimic a rod used in a reactor boiler. The system was tested at different velocities and temperatures to verify it could be used in a range of experiments to try and match …

Inverse uncertainty quantification of trace physical model parameters using Bayesian analysis
… MCMC algorithm, with a particular focus on the subcooled boiling model. The OECD/NEA BWR full-size fine-mesh bundle test (BFBT) data will be used to quantify selected physical model uncertainty of the TRACE code. The BFBT is based on a multi-rod assembly with measured data available for single …

Experimental study of flow boiling under subatmospheric pressures in a vertical square channel
… characteristics and Critical Heat Flux (CHF) in subcooled boiling flows under subatmospheric pressure. Forced convection boiling is a widely used and effective means of heat transfer. An understanding of the mechanisms and limitations involved in forced convection boiling is important for the …

A study of solute transport of radiolysis products in crud and its effects on crud growth on PWR fuel pin
… on the Zircaloy cladding surface exposed to the subcooled boiling length of the fuel rods. The thermal processes in this layer, which result in the holdup of boron (10B and 11B), cause a larger than predicted decrease in the neutron flux. Research suggests that the buildup rate of metallic …

Exploring water-in-oil emulsions for immersion cooling: thermophysical properties, electrical insulation, and chip-level performance
This thesis experimentally evaluates Span 80–stabilized water-in-oil (W/O) emulsions, prepared from Crystal Plus Oil 70T with 2.5–20 vol% water, as immersion coolants for natural-convection cooling of high-power electronics. Conventional dielectric oils provide good insulation but low thermal …
