Heat transfer from molten materials to liquids
… molten metals (aluminium, lead and tin) and sub-cooled water were conducted. The cooling rates of the molten materials under conditions of flooding were measured with a high speed-thermocouple and recorded with a transient recorder. A simplified model for calculating heat fluxes and metal …

An experimental study of critical heat flux with surface modification and its analytic prediction model development
… due to the complex natures of phenomena, CHF in sub-cooled flow boiling is still an active research topic. This experimental study examines the effects of various operating system conditions including; system pressure, mass flow rate, sub-cooled temperature, and surface wettability upon CHF under …

The design of an apparatus to determine the film coefficient of water at high heat fluxes
… of forced convention, local boiling of sub-cooled water and the two phase flow of water-steam mixtures. Inasmuch as the agitating action of the bubbles during boiling of liquid permits high rate of heat transfer, information concerning convective heat transfer under conditions of local …

Numerical and Experimental Investigation of Single and Two-Phase Impinging Jet Heat Transfer
… transfer, effects of superheat of target plate, sub-cooled water and inlet velocity on two-phase impinging jet heat transfer were studied numerical using a mixture model. Moreover, visualization of two-phase impinging jet heat transfer process was obtained. Finally, the numerical results were …

Modeling heat rejection in horizontal smooth round tubes and experimental validation for R1234ze(E), R134a and R32
… divided into 3 zones: superheated, two-phase and sub cooled region. These regions, in general, are considered to be independent of each other and various correlations are available in literature to predict the heat transfer coefficient (HTC) in these regions separately. These correlations, if …

CRUD resistant fuel cladding materials
… boiling facility at atmospheric pressure and sub-cooled boiling conditions, and test a series of samples in simulated PWR water with a high concentration of nanoparticulate CRUD precursors. After testing, ZrC was the only material out of six that did not develop dark, circular spots, which are …

Image Analysis of Air-bubble Injection (Front and Side View) into a Turbulent Liquid Stream
"This study concerns an air bubble injection experiments in a vertical upward annular channel in which a 0.4 mm hole was created to inject the air bubbles into the turbulent stream. Water was used as a testing fluid, and the experiments were performed at atmospheric pressure and room temperature. A …
