Abstract:
The article presents the results of an experimental study of heat transfer during boiling of a stream of water underheated up to the temperature of saturated vapors. The experiments aimed at the study the effect of confined space on the heat transfer intensity during the horizontal flow of water in narrow (along the full vertical extent) channels. Channels with heights of 7.0, 3.0, 0.6 and 0.3 mm were studied. The experiments were carried out at atmospheric pressure, mass flow rates of 127-370 kg/(m2•s), heat flows of 50-4800 kW/m2 and under heating of water at the entrance to the channel by 3

Abstract:
An analytical model of stable subcooled flow film boiling on the front of a horizontal cylinder and a model for the wake region downstream of the flow separation points were developed. The flow and temperature fields upstream of the separation points were represented by a “local-similarity” solution obtained through a rigorous mathematical transformation. The transformed governing equations were solved numerically using a finite-difference scheme. Numerical solutions for the vapor layer thickness, the velocity, and the temperature fields were obtained for both the liquid and vapor layers. The

Abstract:
The austenitic stainless steels are used in nuclear spent fuel reprocessing and waste management plants and the process fluid is nitric acid at temperature up to boiling point. However incorporation of oxidizing ions e.g. fission products as well as corrosion products, in nitric acid stream make the environment highly corrosive to stainless steels. Present work aims to investigate role of process parameters and material parameters (composition and microstructure) on corrosion behaviour of stainless steels. The process parameters studied are temperature, acid concentration and oxidizing ions. I

AbstractScaling caused by sodium carbonate and sodium sulphate salts is a common problem during black liquor evaporation and mills currently have no proper tools to monitor or follow it up. The method proposed enables automatic evaluation of scaling rates and behaviours, together with washing performance, by using measurements that are already available at most mills, such as the boiling point elevation and the overall heat transfer coefficient. The method identified the scaling correctly in most cases, normally >90 %, although fast and sudden scaling proved to be challenging; its performan

Evaporation is a process that involves the removal by vaporization of part of the solvent from a solution, with the objective being to concentrate the solution. In the evaporation of solutions containing biological compounds, the volatile solvent can be water or an organic solvent. Organic solvents are frequently used for antibiotics, steroids, and peptides. Often the solution is under a moderate vacuum, at pressures down to about 0.05 atm absolute [1], which is especially important for heat-sensitive biologicals where the temperature should be as low as possible to minimize degradation.

Abstract Stress Assisted Corrosion (SAC) of boiler tubes and economizer tubes from the waterside is one of the major problems in availability loss and safety of power plants and industrial boilers.

Failure mechanisms involved in waterside SAC surely includes film damage as an important step. To understand SAC, a recirculation loop autoclave facility for high temperature water testing

These films, characterized by inherently low stress, can be deposited without pin-holes. Because of this, DLN films exhibit enhanced corrosion resistance to salt fog, acidic (HCl,

Both metals have about the same corrosion resistance in seawater at temperatures up to 200°C. They have excellent resistance to stress corrosion cracking in boiling seawater, even under the steel coupling condition and the presence of sulfide ions in seawater.

Abstract Hydrogen water chemistry reduces the stress corrosion cracking (SCC) of boiling water reactor components by lowering the corrosion potential. However, the amount of N16 carried into the main steam line increases as the corrosion potential decreases. This is attributed to the reduction of nitrogen-containing species to ammonia, which is more volatile than nitrate or nitrite and readily partitions to the steam phase. An alternative method to lower the corrosion potential and mitigate SCC without large hydrogen additions is in situ noble metal deposition. With this technique, noble metal
