This work deals with the investigation of radiation models for combustion spray. The n-pentane fuel C5h12 is used chemical reactions air. main objective these simulations to compare experimental data and spray select best model. model interpret structure properties prediction combustion. simulated cases are carried out using Ansys Fluent. mixture fracture probability density function evaluate n...

A new type of electron ionization LC-MS with supersonic molecular beams (EI-LC-MS with SMB) is described. This system and its operational methods are based on pneumatic spray formation of the LC liquid flow in a heated spray vaporization chamber, full sample thermal vaporization and subsequent electron ionization of vibrationally cold molecules in supersonic molecular beams. The vaporized sampl...

Ethanol (EtOH) is now produced from fermentation of carbohydrates [1]. Guerbet reaction is a possible way to couple C-C bonds of aliphatic alcohols towards higher carbon skeleton molecules that are suitable for diesel, gasoline, aviation fuel and chemicals [2–4]. When vaporized EtOH is contacted to solids at temperatures near 673.15 K, a lot of different products are obtained containing olefins...

Perfluoroalkyl acids (PFAAs) are a group of persistent organic substances that are surface active and water and fat/oil repellent. Due to the wide use and persistence of PFAAs they are present everywhere in the environment, and humans are exposed via food, drinking water and the use of products containing PFAAs and related compounds. We investigated blood serum levels of ten perfluoroalkyl carb...

In this study, we investigate the effect of presence fuel droplets, their size and concentration, on stretched laminar flame speeds. We consider premixed strained methane/air mixtures, with addition small acetone compare velocity field behaviour to that fully vaporized mixture. An impinging stagnation configuration is used, which a narrowly distributed polydisperse mist droplets added. Total mo...

Foamed surfactant solutions can clean surfaces! We hypothesise that the cleaning efficiency depends on liquid fraction and stability of foam. also is better smaller average bubble size is. The double syringe technique was used to generate foams with varying fractions but same, very small sizes without perfluorohexane in gas phase. performed tests which were applied glass substrates contaminated...
