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.

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 ...

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 ...

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 ...

Thermal management with self-rewetting fluids
Microgravity - Science and Technology, 2005The present paper describes the results of a series of microgravity experiments on thermal management device, actually wickless heat pipes, with using the so-called “self t-rewetting fluids” (dilute aqueous solutions of high carbon alcohols) as a working fluid. Although most of liquids show a decrease in the surface tension with increasing temperature,

THIN-LAYER REWETTING CHARACTERISTICS OF CANOLA
Transactions of the ASAE, 1990ABSTRACT Thin-layer rewetting tests were done for canola in the temperature range of 7.5° C to 30.0° C at two relative humidities (80 and 90%). The thin-layer rewetting rate data agreed with Page's equation. The parameter n in Page's equation was assumed as a product-dependent constant which made it easy to compare the effects of independent variables ...

Rewet of Thermally Bonded Polyester Nonwovens
Textile Research Journal, 1987The effects of web characteristics and test methods on the rewet or backflow of liquids after penetration through the web to an absorptive backing were determined for thermally point bonded webs derived from low melting Dacron® polyester binder fibers. Rewet is influenced by the bulk, wettability, and uniformity of the bonded web.

Abstract Since min = 27kW/m2, then ATmin = 80°C. This is a rather low value, giving a minimum film boiling temperature of 180 °C. In practice, effects such as liquid and surface contamination and the presence of an oxide layer on the surface all tend to increase the minimum film boiling temperature, another term for the Leiden frost ...
