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 ...

Adjustment of Coatings Morphology and Particle Distribution of Layered Silicates by Freeze‐Drying for Improved Gas Barriers

Advanced Engineering Materials, EarlyView.
Freeze‐drying of layered silicate is the key to get coatings with superior gas barrier. Freeze‐drying of layered silicates modified with dodecylamine (DDA) is a highly effective technique for the preparation of barrier pigments that significantly mitigate the permeation of oxygen, water vapor, and hydrogen through polymer films containing these ...

Numerical prediction of the spray from an air-assisted fuel injection system via Eulerian–Lagrangian approach

Energy Reports, 2021
Air-assisted fuel injection (AAFI) systems may be installed in aviation piston engines for atomization of heavy fuels. However, there are few studies on the in-cylinder air-assisted spray characteristics, which affects the improvement of AAFI engine ...

Multimodal Mechanical Testing of Additively Manufactured Ti6Al4V Lattice Structures: Compression, Bending, and Fatigue

Advanced Engineering Materials, EarlyView.
In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting
