TLDR
Le Corre et al. as discussed by the authors performed a literature review of critical heat flux (CHF) experimental visualizations under subcooled flow boiling conditions and systematically analyzed three major types of CHF flow regimes (bubbly, vapor clot and slug flow regime) based on a dimensional analysis of the phenomena and available experimental information.About:

Mechanistic CHF model development for subcooled flow boiling in a vertical rectangular channel under low pressure
TL;DR: In this article, a new mechanistic model is derived to predict the subcooled flow boiling CHF in a rectangular channel for turbulent upward flow under low pressure, which is characterized by its consideration of coalesced vapor clot growth due to bubble coalescence not only in the flow direction, but also in the radial direction.

Subcooled flow boiling at high heat flux
TL;DR: In an experimental investigation of subcooled flow nucleate boiling of water at atmospheric pressure on stainless steel, it was found that the heat transfer coefficient increased with increasing subcooling and also with increasing wall thickness over the range 0.08-0.20 mm as discussed by the authors.

A mechanistic critical heat flux model for subcooled flow boiling based on local bulk flow conditions
C.H. Lee,I.A. Mudawwar +1 more
TL;DR: In this article, a new mechanistic critical heat flux (CHF) model for vertical subcooled flow at high pressure and high mass velocity was developed based on the dryout of a thin liquid layer beneath an intermittent vapor blanket due to a Helmholtz instability at the sublayer-vapor interface.

Critical heat flux
TL;DR: A survey of fundamental studies on the critical heat flux (CHF) phenomenon can be found in this paper, where the materials have been classified into four main boiling modes, subdivided into individual important topics and arranged in a proper sequence so as to show the synthetic framework of the CHF phenomenon.
