A correlation of rewetting data
Nuclear Engineering and Design, 1975Abstract Following a loss-of-coolant accident in a water reactor the fuel pins dry out and overheat and it becomes necessary to rewet them to restore normal temperatures. A thermal conduction analysis of rewetting is presented in which it is shown that the heat transfer coefficient associated with rewetting may be taken as an arbitrary function of ...

Carbohydrate formation in rewetted terrestrial cyanobacteria
Oecologia, 1987In the terrestrial cyanobacterium Nostoc commune Vauch. formation of carbohydrate polymers was measured upon rewetting the mats in a light-dark regime. To discriminate between carbohydrates of different physiological function, total carbohydrate was determined as anthrone-reactive material (ARM) and storage carbohydrate (glycogen) assayed by an enzymic

Annals of the New York Academy of Sciences, 2006
Abstract: This paper reviews a series of my heat transfer studies of on the so‐called “self‐rewetting” fluids, in which the Marangoni effect due to concentration gradient and the thermocapillary flow cooperatively result in a strong liquid inflow at the nucleation sites in the course of boiling. First of all, the background of the study and our first

Capillary Rewetting of Vaned Containers: Spacecraft Tank Rewetting Following Thrust Resettling
AIAA Journal, 2004Recent investigations have successfully demonstrated closed-form analytical solutions of spontaneous capillary flows in idealized cylindrical containers with interior corners. In this work, the theory is extended and applied to complex containers modeling spacecraft fuel tanks employing propellant-management devices (PMDs) consisting of networks of ...

Journal of Agricultural Engineering Research, 1993
Abstract A laboratory rig is described which was developed to investigate the behaviour of partially dried swaths when rewetted by simulated rainfall. Results are given from a series of experiments made using the rig. A previously reported distributed model, representing the rewetting of swaths in the field or laboratory, is developed further ...

Self-Rewetting Fluids with Suspended Carbon Nanostructures
Journal of Nanoscience and Nanotechnology, 2011Thermal management is very important in modern electronic systems. Recent researches have been dedicated to the study of the heat transfer performances of binary or multi-component heat transfer fluids with peculiar surface tension properties and in particular to "self-rewetting fluids," i.e., liquids with a surface tension increasing with temperature ...

REWET-II and REWET-III facilities for PWR LOCA experiments
1989The objective of the REWET research project is to improve the understanding of the basic phenomena of accident situations in nuclear power plants and to provide experimental data for the development and verification of the LOCA and SBLOCA codes. For calculations of the experiments exact data of the facility and the initial state of the experiment must ...

A study on the rewetting temperature
Nuclear Engineering and Design, 1985Abstract The rewetting or quench temperature is the temperature of a hot solid surface at which a liquid can reestablish contact with the dry surface. An estimation of this temperature is essential in predicting the rate at which the coolant quenches the core of a light-water reactor (LWR) after a loss-of-coolant accident.

Rewetting of hot horizontal tubes
Nuclear Engineering and Design, 1992Abstract Experiments on the rewetting and refilling of hot horizontal tubes are presented. The experiments were carried out under a wide range of initial and boundary conditions. The effect of tube wall thickness, initial wall temperature, inlet mass flux and inlet subcooling were investigated.

Rewet in wet pressing of paper
TAPPI Journal, 2018Wet pressing in papermaking removes water by pressure applied over time, but some of the expelled water may return to the web in an action called “rewet.” This water, and the other remaining water, must be removed by drying. To understand the underlying factors of rewet, we have developed a mathematical model of it comprised of a time-dependent term ...
