A 3-D CFD model based on KIVA 3 code is developed with a “reduced” detailed chemical kinetics of 291 elementary reaction steps with 79 chemical species for diesel fuel combustion. The model was validated by the corresponding experimental results and employed to examine some important parameters which have significant effects on the engine performance for an IDI diesel engine with a swirl chambe...

The dependences of the protective properties anodic oxide coatings on AD31 aluminum alloy surface modified with nitrates magnesium, potassium, and some 3d-elements composition sealing solutions parameters finishing treatment were established by scanning electron microscopy, potentiodynamic polarization, electrochemical impedance spectroscopy, salt spray chamber tests. A mechanism formation duri...

In the present paper, formation of protective coatings on MA8 magnesium alloy by plasma electrolytic oxidation (PEO) with subsequent treatment fluoropolymer is considered. The morphology after accelerated climatic tests was investigated and elemental composition studied in a salt spray chamber (SSC). analysis obtained results demonstrated higher corrosion resistance fluoropolymer-containing lay...

A statistical design of experiments for a rotary fluidized bed agglomeration process is performed to improve both the knowledge and influence parameters. Agglomerates pharmaceutical formulation are manufactured in laboratory rotor apparatus with tangential spray nozzle. Particle size measured in-line over entire spatial filter velocimetry probe installed directly chamber off-line dynamic image ...

Small particles are of great interest in a variety applications. Spray drying is common technique for particle synthesis, but it limited with respect to sizes below 10 μm. Therefore, new laboratory-scale spray dryer was designed address this issue. A novel aerosol generator consisting piezo crystal swirl chamber obtain droplets the low micrometer range. After and cooling, were deposited molten ...

The total volatile organic compound (VOC) content and VOC composition of 12 consumer products is determined using the headspace method chamber testing. Several hazardous or toxic VOC’s are present in abundance. Some from same category vary significantly terms species. Spray adhesive for this study have high contents. results show that three spray adhesives low moisture (0-35.87 wt.%) a (63.41-9...

In this paper, the effect of atomizer geometry on the flow in simplex atomizers and atomizer performance is numerically investigated. A computational model based on the Arbitrary-Lagrangian-Eulerian method has been used. The effect of changes in four non-dimensional geometric parameters on the atomizer performance is studied. These geometric parameters are the atomizer constant (ratio of inlet ...

Some unicellular organisms present challenges to chemical fixations that lead to common, yet obvious, artifacts. These can be avoided in entirety by adapting spray-freezing technology to ultrarapidly freeze specimens for freeze substitution. To freeze specimens, concentrated suspensions of cells ranging in diameter from 0.5-30 pm were sprayed with an airbrush at 140-200 kPa (1.05-1.5 torr; 20.3...
