Comparison of the Characteristics of Sprays between Water and Nanofluid Sprays

Journal of ILASS-Korea, 2014
Abstract Nanofluids is that metallic or nonmetallic nanometer-sized particles are dispersed in liquid and they can be used in variousfields to increase the heat transfer rate. This study conducted experiments to evaluate whether the cooling efficiency of nanof-luids is better than that of water in spray cooling.

Analysis of Spray Flow Pattern and Spray Combustion Characteristics.

Journal of the Fuel Society of Japan, 1991
The analysis of spray flow was very important for the spray combus-tion simulation. In this study, the models for the spray pattern and the motion of spray dro-plets in the gas flow were investigated to improve the simulation accuracy. The spray pat-tern was expressed by the random sampling of spray angles from a normal probability de-nsity ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Experimental Investigation of Spray Characteristics in Subsonic Crossflows [PDF]

, 2013
The breakup of a liquid jet, in a crossflow leading to the evolution of the spray plume downstream is an important aspect that needs to be well understood for improving combustion efficiency and reduction of emissions for airbreathing propulsion engines.
