Critical Exponent for the Density of Percolating Flux

, 1993
This paper is a study of some of the critical properties of a simple model for flux. The model is motivated by gauge theory and is equivalent to the Ising model in three dimensions. The phase with condensed flux is studied.

A Novel Role of Three Dimensional Graphene Foam to Prevent Heater Failure during Boiling [PDF]

, 2015
We report a novel boiling heat transfer (NBHT) in reduced graphene oxide (RGO) suspended in water (RGO colloid) near critical heat flux (CHF), which is traditionally the dangerous limitation of nucleate boiling heat transfer because of heater failure ...

Thermal signatures of Little-Parks effect in the heat capacity of mesoscopic superconducting rings [PDF]

, 2006
We present the first measurements of thermal signatures of the Little-Parks effect using a highly sensitive nanocalorimeter. Small variations of the heat capacity $C\_p$ of 2.5 millions of non interacting micrometer-sized superconducting rings threaded ...

Enhancement the Performance of Steam Generation Power Plants

Journal of Engineering and Sustainable Development, 2005
This paper deals with the study of the mechanism of heat transfer between the combustion of hot gases and water inside steam generator. The operating conditions in these applications are designed to maintain heat flux lower than critical heat flux (CHF)

Prediction models of critical heat flux for vertical downward flow

Nihon Kikai Gakkai ronbunshu, 2017
Critical heat flux is one of the most important key parameters for various boiling systems, such as nuclear reactors and conventional boilers. Thus, many investigations have been reported, but most of these are concerned with the upward flow condition ...

Theory of the vortex matter transformations in high Tc superconductor YBCO

, 2003
Flux line lattice in type II superconductors undergoes a transition into a "disordered" phase like vortex liquid or vortex glass, due to thermal fluctuations and random quenched disorder.

Measurement of the SOC State Specific Heat in ^4He [PDF]

, 2006
When a heat flux Q is applied downward through a sample of liquid 4He near the lambda transition, the helium self organizes such that the gradient in temperature matches the gravity induced gradient in Tlambda. All the helium in the sample is then at the
