Late-evaporating liquid fuel wall-films are considered a major source of soot in spark-ignition direct-injection (SIDI) engines. In this study, model experiment was developed to visualize formation the vicinity evaporating films. Isooctane is injected by multi-hole injector into optically accessible part constant-flow facility at atmospheric pressure. Some impinges on quartz-glass windows and f...

We present a detailed set of measurements from a piloted, sooting, turbulent C2H4fueled diffusion flame. Hybrid femtosecond/picosecond coherent anti-Stokes Raman scattering (CARS) is used to monitor temperature and oxygen, while laser-induced incandescence (LII) is applied for imaging of the soot volume fraction in the challenging jet-flame environment at Reynolds number, Re = 20,000. Single-la...

A three-dimensional laminar non-buoyant diffusion flame was studied with the objective of improving the understanding of the soot production. The flame originated from a porous ethylene burner discharging into a laminar boundary layer. Soot volume fractions were measured using Laser-Induced Incandescence (LII) and the spontaneous emission from CH∗ was determined using chemiluminescence. The mai...

Present study is carried out for the removal of As(lII) from water using commonly available adsorbents such as sand, from Yamuna river (Delhi ), as well as from Ganga river (Kolkata), activated carbon, Hametite ore and sand -iron scrap mixture. All these adsorbents are used as received but sand and activated carbon which do not show much adsorption for As(lII) are modified by treating with diff...

19 Listeria monocytogenes is a foodborne bacterial pathogen and the causative agent of 20 human and animal listeriosis. Among the three major genetic lineages of L. monocytogenes (i.e. 21 LI, LII, and LIII), LI and LII are predominantly associated with foodborne listeriosis outbreaks, 22 whereas LIII is rarely implicated in human infections. In a previous study, we identified a 23 Crp/Fnr famil...

Defect detection in ferromagnetic substrates is often hampered by nonmagnetic coating thickness variation when using conventional eddy current testing technique. The lift-off distance between the sample and sensor one of main obstacles for measurement coatings on Based thin-skin effect insensitive inductance (LII), a simplified iterative algorithm proposed reducing multifrequency sensor. Compar...

* Corresponding author: [email protected] International Discussion Meeting and Workshop 2006: Laser-induced Incandescence, Quantitative interpretation, modelling, application Introduction Time-resolved LII has recently evolved into a tool for evaluating particle size distributions in aerosols. Since larger particles cool slower than smaller particles the size distribution can be recovere...
