A unifying criterion of the boiling crisis [PDF]
We reveal and justify, both theoretically and experimentally, the existence of a unifying criterion of the boiling crisis. This criterion emerges from an instability in the near-wall interactions of bubbles, which can be described as a percolation ...

Dataset for boiling acoustic emissions: A tool for data driven boiling regime prediction [PDF]
Boiling is used for the thermal management of high-energy-density devices and systems. However, sudden thermal runaway at boiling crisis often results in catastrophic failures.

The investigation of boiling crisis of nanofluids [PDF]
Saturated boiling of nanofluids on a cylindrical heater with different diameters is experimentally studied. Studied nanofluids were prepared using distilled water and different metal oxides nanoparticles. The volume concentration of the nanoparticles was

Deep learning the sound of boiling for advance prediction of boiling crisis
Summary Advance prediction of boiling crisis is critical to the safety and economy of many thermal systems. Here, we perform steady-state near-saturated boiling experiments on a plain copper surface and acquire the acoustic emissions (AEs) in natural convection, nucleate, and transition boiling regimes.

Boiling crisis due to bubble interactions
Abstract The boiling crisis determines the maximum heat flux for the safe operation of boiling equipment, which is widely used in various applications including power generation, thermal management of electronics and water desalination. Here we present a mechanistic and predictive theory for the boiling crisis, combining the thermo-fluidic ...

Multimodal boiling dataset with synchronized acoustic, optical, and thermal measurements under steady-state and transient heat loads [PDF]
Boiling is a high-performance heat dissipation process that is central to electronics cooling and power generation. However, there exists a practical limit of boiling heat transfer known as the critical heat flux (CHF), beyond which significant ...

Large-scale fluctuations during a boiling crisis and during the boiling up of a superheated liquid jet [PDF]
The results of an experimental study of pulsation processes during the transition from nucleate to film boiling on a wire heater and in transient regimes of boiling up of a liquid jet flowing from a high-pressure chamber are presented.

The influence of microstructured surfaces and liquid pulsations on increasing heat transfer in a minichannel [PDF]
The paper compares two methods for improving the intensification of heat transfer during boiling in a rectangular minichannel. Studies were carried out of the influence of additive structures on the crisis of heat transfer in a minichannel with a two ...

Boiling Crisis as a Critical Phenomenon [PDF]
We present the first experimental study of intermittency and avalanche distribution during a boiling crisis. To understand the emergence of power law statistics we propose a simple spin model capturing the measured critical exponent. The model suggests that behind the critical heat flux is a percolation phenomenon involving drying-rewetting competition

The heat transfer rate during nucleate flow boiling conditions inside a horizontal heated pipe is assumed to increase with the heat flux until the boiling crisis while being independent of the mass flux.
