Calculations on the rewetting of hot surfaces
Nuclear Engineering and Design, 1974Abstract Previous theoretical and experimental work has shown that the rate of advance of a quench front over a hot surface is a function of the initial temperature, the thickness and the physical properties of the hot surface, and the cooling water flow conditions.

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,

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 ...

Response of osmolytes in soil to drying and rewetting
Soil Biology and Biochemistry, 2014Abstract The accumulation and subsequent release of microbial osmolytes in response to drying and rewetting are thought to be key players in C and N dynamics, yet studies on soils have failed to support this hypothesis. The aim of this experiment was to determine how low-molecular weight compounds, and osmolytes in particular, are affected by drying ...

Rewetting of drained agricultural land is expanding across Europe to meet climate and biodiversity targets, yet the relative roles of post‐rewetting management and restoration age in shaping vegetation remain poorly resolved. We surveyed vascular plant communities and soils in 69 plots across 12 rewetted former croplands (6–22 years since rewetting) in

Navigating the transition to rewetted peatlands
This cumulative dissertation analyses the rewetting of agriculturally used peatlands in Germany as a socially acceptable and climate-target-compliant transition. The dissertation highlights that rewetting is a task for society as a whole, involving a profound, multidimensional transition.openaire +1 more source
Rewetting processes during PWR reflood
2011Rewetting of heated surfaces is important in many physical processes and has important technological applications. Understanding of this phenomenon is required in many engineering and scientific fields. It is one of the most crucial phenomena to be considered for the safety analysis of the design basis Loss‐of‐Coolant Accident (LOCA) in light water ...
